GENERAL SUiViMARY OF THE PORK OF THE SESSION

------TIME AND PLACE OF THE SESSION The second session of Regional Association V was held in the Rizal Hall of the University of the Philippines, at Manila from 7 to 18 April,· 1958. Faci­ lities for the session, including interpretation, were provided by the Phi­ lippine Government.

OPENING OF THE~ESSION (Agenda item 1)

The formal opening of the session took place on Monday, 7 April, 1958, at 10 a.m. in the Little Theatre of the University of the Philippines, at Manila e Mr. Del Rosario, president of the association, welcomed the delegates of the session. He stressed the importance of the agenda which was to be considered by the session. Mr. MoA.F. Barnett, First Vice-President of the WMO, conveyed to the session the greetings and best wishes of the President of the Organization, Mr. Ao Viaut. He stressed the difficulties of the problem that were facing the Re­ gion as a result of the fact that the greatest part of the Region is taken up by oceans. He invited the attention of the session to the problems facing meteorology as a result of the developments taking place in aviation. Finally Mr. Fo Serrano, Secretary of Foreign Affairs, officially opened the session and in his address, emphasized the importance of meteorology for eco­ nomic development, stressing in particular its functions with respect to agriculture.

ORGANIZATION OF THE SESSION

2.1 Examin2~jon_of credentials (Agenda item 2.1) The first plenary.meeting of the session was presented with a complete list of the delegates representing Members of Regional Association V for which ap­ propriate credentials have been received. As no objections were raised to the credentials as such,the association agreed that it was not necessary to establish a credentials committee. 2 GENERAL SUIvliViARY

3.2.1 The session considered the report of the chairman of the working group with appreciation of the work performed by it 00 its terms of reference under Re­ solution 15 (I-RA V). 4 GENERAL SUMMARY

3.2.2 The session considered that there was a sufficient number of important prob­ lems in the field of meteorological telecommunications requiring detailed study by meteorological experts in liaison with telecommunications experts . to justify the re-establishment of the working group by the associ(ltion and the specification of its terms of reference. Resolution 16 (II-RA V) was adopted and Resolution 15 (I-RA V) cancelled. .

- 4. INSTRUMENTS

4.1 Regio.0~U9.lE'pariso.0--2L ba.E2~ers (Agenda item 401) The session noted with satisfaction that the barometers of Malaya, New Zealand, the Philippines and the United States of America have been compared with the Australian Standard barometer, using the method of comparison set

out in Recommendation 15 (CIivlO- I) 0 It VIas a Iso noted that a comparison had been made between the Indonesian and Indian barometers, and that plans exist for a comparison between Portuguese Timor and Australia. A comparison be­ tween the barometers of Netherlands New Guinea and the Philippines was car­ ried out during the second session. The session expressed its appreciation for the Australian leadership in this field and decided to maintain Resolution 1 (I-RA V) in force. No formal re­ commendation or resolution was adopted on this subject.

5. OBSERVATIONS FOR THE PURPOSE OF SYNOPTIC METEOROLOGY

5.1 Study of the existing network of land stations for surface and upper-air ob­ servatlonsandestablishmentoT-a recomiIiei1decr r.egional network------­ =(p:genda :Ltem50T)------~------

5.1.1 The session·examined the network established by Resolution 2 (I-RA_V), to­ gether with relevant recommendations of the International Civil Aviation Organization and suggestions of Members.

5.1.2 The session noted that stations 91115, Iwo Jima, and 91131, Marcus Island, are within the area of Regional Association II. They were deleted from the GENERAL SUMMARY 5

Region V network with the understanding that they would be included in the basic network of Region II.,

5.103 The session established the basic surface and upper-air network in Resolu­ tion 1 (II-RA V)? calling upon Members to implement the network as a matter of urgency.

5.1.4 The session noted that in some cases surface synoptic observa-tions are made at times' which depart to some extent frOlil' the standard times. It urged that Members endeavour to conform to the standard times of observation.

5.1.5 Realizing the difficulties of, establishing facilities to meet new require­ ments~, the session agreed that stations included in the basic network'should be limited to those required f6r:rendering particular services~ and for which implementation is reasonably practicable. With particular reference to the requirements of the International Civil Aviation Organization, the network was d~signed to provide the synoptic data and information considered necas· sary for furnishing the standard meteorological services for existing: and planned operations. Resolution 1 (II-RAV) was adopted on this subject.

5.2 1n-flight ~ES?rt,§2££~.L_~ir.9:2ft (Agenda item 5.2) 5.2.1 The session examined the international procedures governing air reporting? as well as the Paci'fic and South-East Asia regional supplementary procedures as applicable to Regional ,Association V, with a view to establishing the de­ tailed meteorological requirements in regard to air reporting in Region V. Special attention was devoted to air reporting byhigh-speed/high-flying air­ craft and to the relative value of post~flight versus in-flight reports. This examination was carried out on the understanding that such observations are essential for adequate meteorological service for safe and efficient civil air navigation. Recommendation 4 (II-RA V) was adopted 00 the subject.

5.2.2 In order to obtain factual ~,nformation regarding the udequacy of the air re­ porting scheme in the Region; the ~ession decided? at the invitation of the Exec~,tive Committee, to ask its Members to assemble statistics on the number of air reports received from aircraft~ Resolution 4 (II-AR V) was adopted on this subj ect 0 6 GENERAL SUIV1MARY

5 0 3 Qbserva,!ions from ships and~~tati~ (Agenda item 5.3)

5.3.1 Under this item, the session considered both the questions of establishment of ocean weather stations and of reports from ships at sea,

5.3.2 Concerning establishment of ocean weather stations in the Region the session recognized this as a desirable means of augmenting networks~ but concluded that it would not be economically practicable at this time.

5.3.3 With respect to reports by merchant vessels, the sess.ion noted the actions taken by the Executive Committee in Resolutions 33 and 36 (EC-IX) on the re­ levant recommendations of the second session of the Commission for Maritime Meteorology and that the Secretary-General had been requested to approach all Members of the Organization in order to obtain implementation of the measures proposed. The session also considered the request of the Commission for Maritime Meteorology that regional associations examine Resolution 10 (I-RA I) dealing with weather reports from ships other than selected ships. It was considered that the situation in Region V did not call for such ac­ tion.

5.3.4 Special attention of the Members of the Region is called to the lack of ship reports in the areas east and south-east of the Hawaiian Islands and south and east of the Philippines. It was agreed.to invite all Members of the Re­ gion whose ships ply these waters, to arrange for transmission of meteoro­ logical reports to the appropriate collecting centre. No formal recommendation or resolution was considered necessary on this item.

5.4 ~~to~'!1c we~ther sl~tiQ0~ (Agenda item 5.4)

5 0 4.1 The session was informed of the progress achieved in the development of au­ tomatic weather stations, in particular by Australia, France and the United States, and of the experience gained with such stations in the Region. It _ noted that some Members plan to install additional automatic weather sta- tions in the near future. . While it was considered premature to establish a specific regional network of automatic weather stations, it was agreed that Members should be encouraged GENERAL SUMMARY 7

'. to continue their experiments with such stations and to install them in ap­ propriate locations. It was noted that~ by its Resolution -3 (CIMO-II) ~ the CIMO had decided 'to prepare a summary of available equipment and Members are invited to collaborate. .

5.4.2 With respect to Resolution 33 (58-RA V)~ regarding hourly observations at isolated island locations, which was adopted as a result of Recommendation 3 of the MET Committee of the First Pacific Regional Air Navigation Meeting, the session agreed that automatic weather stations were not 'yet capable of meeting fully the requirements expressed in that resolution.

5.4.3 Finally, it was noted that the Commission for Climatology had stated that there is a clear need for the establishment of automatic climatoiogical sta­ tions, particularly in land and sea areas for which climatological informa­ tion is sparse. It was felt, however, that the automatic weather stations so far available are not entirely suitable for this purpose.

5.4.4 No formal resolution or recommendation was considered necessaryG

5.5 Observations_QLat!!!232he£i:~ (Agenda item 5.5) The:.session considered this iteri1 in the light of Resolution 23 (EC .. IX). It- 'noted with interest the successful experiments that had been carried out with atmospherics during recent years in Australia, as well as the plans to enlarge the already existing network. The United States had had considerable experience in this field in other Regions, and plans the establishment of a network in the Pacific area~ by approximately 1960, which will extend into Region V• .The hope was expressed that other Members would find it practicable to install such observation equipment within the Region. No formal resolution was a'dopted on this subj ect because the recently adopted Resolution 36 (58- RA V), developed as a result of Recommendation 16 of the MET Committee of the First Pacific Regional Air Navigation Meeting, adequately covers the subj eet.

5.6 .Qf~d rad~f~ath~-2bs~~1:2!2~ (Agenda item 5.6)

5.6.1 The session noted that since the first session of the association consider­ able experience had been gained in the use of ground radar weather observa­ tions, and that a considerable number of new sets had been installed in the 8 GENERAL SUMMARY

Region. It was agreed that the Members of the association should be encourag­ ed to install additional sets, but that it is premature to establish a spe­ cific network on a regional basis. The delegate of Australia stated that some Australian merchant vesselS make and report weather observations made with the ship radar sets. The session expressed the hope that other Members would find it possible to introduce this practice. Finally the meeting was of the opinion that it would be useful if Members making radar weather observations on a routine basis would inform the \Torld Nleteorological Organization Secre­ tariat of the location of these stations for publication in Volume A of WMO p1.,lblication No.9.

5.6.2 With regard to the exchange of radar weather observations, the session agreed that the need for at least a regional code was increasing but that it appear­ ed desirable to obtain first more accurate scientific knowledge about the in- .. terpretation of ground radar echoes. The session therefore decided only to encourage the continuation of experiments on a national basis and not to take specific action on exchange of observations.

5.6.3 The conclusions of the session are contained in Resolution 3 (II-RA V).

5.7 1l0moge.!}~itY_

5.8 Horizontal~.2~~9ings (Agenda item 5.8) The session noted that in its Resolution 20 (EC-IX) the Executive Committee had recognized the potential value of horizontal sounding techniques and had recommended that regional associations in the Southern Hemisphere should ex­ plore the practical possibility of using existing transosonde technique~. The session agreed that use of these techniques in the Southern Hemisphere would be desirable, particularly along approximately the 55° south latitudinal GENERAL SUMMARY 9

belt, INhere the conditions imposed by 2esolution 20 (EC-IX) would be entire­ ly met. While recognizing that horizontal soundings techniques constitute a desirable means of augmenting the data obtained from the ground basic network, it con­ cluded that such a scheme would not be economically practicable at this time in the Region.

6.1 Use....£.L.!..1:~~.Y!l0E.~.ic~ode.§.._.il}._~..-..!-ropics (Agenda item 6.1) The session noted that the president of the Commission for Synoptic Meteoro­ logy had conducted an inquiry amongst the members of his commission concern­ ing the use of the synoptic codes in the tropics, but that few Members of '. Regional Association V had replied to that inquiry. It was also noted that the second session of the Commission for Synoptic Me­ teorology had established a working group. to study all code problems and that provision was made' for a representative of Regional Association V on this working group • . In· view of the above, ·the session decided to request the Membel's ,of Region V to study in detail and as a matter- of urgency the question of the use of synoptic codes in the tropics and to elaborate specific proposals for report­ ing to the president of the association, for the benefit of the region V re­ presentative on the CSM Vlorking group. The session also reconsidered Recom-. mendation 3 (I-RA V) regarding code specification for jajpjp in code form .' FM 1,LA with respect to tropical areas. It was noted that this recomnienda-': tion: hEld 'been .referred to the Commission felT Synoptic Meteorology andwo'uld theref'ore be considered by the CSM working group on codes problems but i-t was nevertheless decided to maintain this recommendation in force.

602.1 The session completely reviewed the coding practices within Region V in the light of Resolution 7 (CSiVi-II), and Recommendations 5, 8, 41 and 53 of the second session of ·the Commission for Synoptic Meteorology, although aware that the recommendations had still to be considered by the Executive Commit­ tee. In line with the new policy of the Organization as contained in Resolu­ tion 3 (EC-VIII), the session unanimously adopted amendments to the text 10 GENERAL SUMMARY

appearing in Section V, Chapter II, Volume B of WMO publication No~ 9, in. the form of an annex to Resolution 5 (II-RA V)~

6.202 The session in its considerations gave priority to the requirements of the main analysis centres of Region V (see Resolution 9 (II-RA V)) for the prompt reception of the upper-air reports they need for the preparation of the upper­ air analyses for which they are responsible. The session felt that priority to the requirements of the main analysis centres of Region V would be met without restricting the individual needs of Members in tropical areas who at present prefer raw data to processed data. The session concluded that adop~ tion of the ABTOP form of messages used in Region VI with slight modifica­ tions would meet needs of the main analysis centres.

6.2.3 The session then reviewed the selection of levels for which upper-air data were required in regional exchanges, particularly for the purpose of eliminat­ ing the inclusion of unnecessary data in territorial and subcontinental broad­ cast messages. In doing so it was concluded that radiosonde data reported in the ABTop messages should not be repeated in TEMP messages and that upper-wind data should be reported for all selected levels in PILOT messages, as well as for the "analysis" surfaces in the ASTOP messages. The only alteration made by the session in the present regional practice in the use of the SYNOP form of report was to provide for national choice in the use of the group ldwd P H in reports from coastal stations and lightships. w w w

6.2.4

The~ession recognized thatpuisuant to the aforesaid resolutions and recom­ mendations of the second session of the Commission for Synoptic Meteorology, there were coding problems requiring continuing study by the association and therefore decided that an appropriate working group be established for this purpose. Resolution 5 (II-RA V) was adopted on this subject. 6.2.5 In regard to the question of units used in meteorological reports, the ses­ sion confirmed the desirability of a 'rapid transfer to the Celsius degree and the.. m,et.riJ;; system .Qf units but found it impracticable at this stage. t() fix. a date for the implementation of Resolution 28 (Cg':' II). It was noted that Ihdo­ nesia had decided to adopt the Celsius degree in itsSYNOP reports withiha few months.

6.2.6 The session decided that Resolutions 6, 7, 8, 9 C!nd 10 (I-RA V) be cancelled but that Recommendation 3 (I-RA'V) should be retained because the Commission for Synoptic Meteorology has not yet determined this problem. GENERAL SUMMARY 11

7. TELECOMMUNICATIONS.- 7.1 ~~s of the different tY~.2i..!!lessa~ (Agenda item 701)

In considering this item 9 the session reviewed the work of the association's Working Group' on meteorological telecommunications a,nd the present agreements as recorded in standing resolutions~ The session found that it was necessary to alter the previously agreed contents of the territorial and subcontinental broadcast messages to meet some new requirements and also to reduce the quan­ tity of information being broadcast in the Manila subcontinental messages. A requirement for the reception of some reports from the Hawaii area was speci­ fied by French Polynesia which, it is expected, will be met by negotiation with New Zealand and the United States. The contents of the territor~al and subcontinental broadcast messages as now planned cover the entire area of Re­ gional Association V excepting for the remote north-east part. The conclusions of the session are contained in Resolutions 7 and 8 (II-RA V).

'7.2 '

Establishment of a reqional plan for the eX.9..banCJ!_.S2f m~te.2!.21o.9lcal observa­ !ion~-~Agenda-1tem 7.2) -----

7.2.1 In considering this item, the session took account of Recommendations 35, 37 and 42 (CSM-II) but was aware that they had still to be considered by the Executive Committee.

702.2 The s~ssi6n completely reviewed the present plan of Regional As~ociation V for the exchang,e of meteorological observations within the Region and found that it was essential to specify standards for the transit times of the me­ teorological messages over the various component links in'the meteorological circuitry between the reporting stations and the subcontinental broadcasting centres.

7.2.3 The session reaffirmed as its policy the use of radio-teleprinter form of transmission for territorial and subcontinental broadcast messages particular­ ly in view of the rapidly decreasing use of manual morse operations as a tele­ graphic facility generally.

7.2.4 The session also reaffirmed its policy that the establishment of a continent­ al broadcast centre in Regional Association V was impracticable and indeed 12 GENERAL SUMMARY

was not required because the subcontinental broadcast system of the Region is organized so that a regional coverage of observations is available by in­ terception of three subcontinental broadcasts in their sequence order_ ,D£, emission as planned? and as now existing in respect of two of these broad­ cast centres.

7.2.5

The session determined guiding principles for the use of point~to-point cir­ cuits for the transmission of synoptic meteorological messages when the nor­ mal transmission circuits are inadequate. The conclusions of the session are contained in Resolutions 10, 11, 12 and 13 (II-RA \/) •

'7.3 lransplssion BEocedures (Agenda item 7.3)

7.3.1

The session revised the transmission procedures recently adopted by the ~s­ sociation in the light of Recommendations 46, 47 and 48 (CSM-II) and took account of Recommendation 13 of the first session of the CSM Working Group on telecommunications. The association was aware that the Commission for Synoptic Meteorology recommendation had still to be considered by the Execu- tive c'ominTttee 0 ' ,

7.3.2 The session considered it premature to specify procedures for radio-facsimile transmissions and did not regard it as necessary at this stage to adopt for general use throughout Region V the abbreviated headings authorized by Re­ solution 20 (EC-IV) nor the "dead traffic" procedure for 'meteorological mes­ sages transmitted over the AFTN as developed by the International Civil Aviu­ tion Organization. However, the session considered that when it is necessary for Members to use procedures for the two purposes they shall be those pres­ cribed by the W()rld Meteorological Organization and the International Civil Aviation Organization re,sp,e'ctively. . ".; . . 7.3.3 The conclusions of the session on this item are contained in Resolution 14 (II-RA V).

, 7.4 ]~ch2~~_wi~hneighbo~ri~g Regions (Agenda item 704)

7.4.1 The session considered this item against the background of standing recom­ mendations and resolutions of the Organization on the matter and the GENERAL SUMMARY 13 statements of the requirements of Regional Association V Members and of other Regions for the exchange of meteorological information.

7.4.2 The session reaffirmed the policy of the association to be that the estab-" lishment of a continental broadcast centre in" Regional Association V capable of satisfying the needs for inter-regional exchanges was" impracticable and that suitable point-to-point telecommunications should be used for this pur­ pose.

7.4.3 The session took account particularly of Recommendations 37 and 38 (CSM-II) on the planning of facilities for hemispheric and global exchanges. The ses­ sion was aware that the recommendations had not yet been considered by the Executive Committee. The session decided that the requirements of Region V Members should be studied by the RA V Working Group on meteorological tele~ communications and ultimately made known to the Commission for Synoptic Me­ teorology.

7.4.4 The session recommended that certain improvements of meteorological broad­ ca~ts in Regional Association II should be referred to that association so" "that"" difficulties now experienced in their reception in Regional Associa­ tion V might be overcome. The conclusions of the session are "contained in Re"solution 15 (II-RA V) and Recommendation 2 (II-RA V) •

7.5 Review-2i-the-E~2D~l plan for~he exch2nge of analY2es (Agenda item 7.5) 7.5.1 The session completely reviewed the plan for the exchahgeof analyses. In doing so i.t" ,noted that the plan of the first session of the association for uppe:i>:'air analyses was very far from being implemented and that in fact there was not a:complete coverage for even one upper level over the Region. " The mai~"reasonsfor this position were stated to be lack "of upper-air observa­ tion,chiefly"radiowind 9 and lack of" generally acceptable techniques for tro­ piccH analysis.

7.5.2 It was evident to the session that it was opportune now t~include in the plan specifications for the exchange of prognoses in view of the n~ed for this information in forecasting and briefing for air transport operations, particularly over long distances. Standard times for the dissemination of" analysis and prognosis messages were also redetermined by the session. 14 GENERAL SUMivlARY

7.5.3 The session concluded that the development of tropical analysis techniques should be undertaken on an experimental basis at a suitable centre in the Region and requested Australia to establish such a centre. The session urged" the procurement of radio-facsimile equipment by all its Members as the only satisfactory means of transmitting streamline isotach analyses~ in accord­ ance with Recommendation 36 (CSM-II).

7.5.4 The conclusions of the session are contained in Resolutions 9 and 18 (II-RAV) and Recommendation 1 (II-RA V).

------MARITIME METEOROLOGY 8.1 Collection ar~as for~~ip~_obser~atlon~ (Agenda item 8.1)

8.1.1 Since no complaints had been made regarding the collection areas for ships' observations within the Region~ the session agreed that the existing arrange­ ments ~specified by Resolution 37 (CD rJashington~ 1947) are still adequate. To take account~ however~ of an existing situation~ it was agreed to recom­ mend to the Commission for Maritime Meteorology that the collection area"as­ signed to Malaya be expanded some degrees to the west (see Recommendation 3

(II-RA V)) 0

8.1.2 With reference to Resolution 3 (I-RA V) which allows ships in Region V to transmit their observations to coastal stations of their choice, the sess ion noted that the Commission for Maritime Meteorology had been instructed by the Executive Committee to examine the desirability of world-wide adoption of a similar procedure. The difficulty in the Region is that on some occa­ sions~ ships are unable to contact a shore station located in the collecting area in which they are plying. The session was therefore of the opinion that when a ship encounters such difficulty, it should be permitted to pass its report through a coastal station located within an adjacent collecting area. It was agreed to request the president of the association to bring the above views to the attention of the president of the Commission for Maritime Me­ teorology.

8.1.3 Finally~ with respect to Recommendation 43 (CSM-II) dealing with the stan­ dardization of addresses for ship weather messages, it was considered that GENERAL SUMMARY 15 the association should await the action of the Executive Committee on the re­ commendation.

8.2 Be~i2Dal_~2!21nation o1-Er02dc~s fo!-~bipping (Agenda item 8.2) 8.2.1 The session noted that the broadcast plan established by Resolution 37 (CD Washington, 1947) had been fully implemented within the Region, and that ap­ parently no complaints had been received from shipping interests regarding its adequacy. It was therefore agreed that no changes were required in the existing plan.

8.2.2 With regard to the reporting of winds, attention of the Members 9f the asso­ ciation was invited to the revised descriptive terms of Beaufort numbers 7, 8, 10 and 11 recommended by the Commission for Maritime Meteorology (see Re­ commendation 2 (CMM-II)) and approved by the Executive Committee (see Resolu­ tion 35 (EC-IX)).

8.2.3 Finally, the session noted that the Commission for Synoptic Meteorology had developed a short forecast code for issuing weather forecasts when English cannot be used (see Recommendation 3 (CSM-II)).

8.3 Port liaison off~ (Agenda item 8.3) In examining this item,. the session noted that the Commission for Maritime Meteorology has highlighted the importanc~ of the furictiori ~f th~ port ma­ teorological liaison officers as a meansofiinpr6virig the quality and humber of reports from merchant ships. While noting that it may not always be poss­ ible to appoint such officers from amongst persons having maritime experi­ ence, it was agreed that Members should be encouraged to improve, where ne­ cessary, . the liaison between meteorological services and shipso It was not considered useful for the association to establish a list of ports where port liaison officers should be appointed. Finally the meeting noted that the Commission for Maritime Meteorology had emphasized the importance of having shipsl observations of clouds and me­ teors. While noting that some Members of·the association had distributed. the Abridged Cloud Atlas to their selected ships, the session wished to express strong support for the early preparation of a simplified version of the Abridged Cloud Atlas as contemplated in Recommendation 25 (CMNi-II) and Re­ solution 33 (EC-IX). No formal resolution or recommendation was adopted on this item. 16 GENERAL SUMMARY

8.4 freation_of a ti2~1 wave warninE-syste~ (Agenda item 8.4) The association noted that in Resolution 38 (EC-IX) the Executive Committee had already laid down a complete plan of action for investigating the possibi­ lity of setting up an international tidal wave warning system. The difficulties involved in such a warning system are many ~ such as the necessity for an ade­ quate observing network~ and for speedy transmission in view of the extremely high speed at which some pf these waves travel. But above all the problem is not a purely meteorological·one and calls for co-ordinated action between me­ teorological services and other services working in the field of geophysical sciences. In this respeci:;~ . it was noted that the Executive Committee had call­ ed for joint consideration of the problem between the World Meteorological Organization and the International Union of Geodesy and Geophysics. Note was taken of the fact that the Secretary-Genera1 9 acting under instructions of the Executive Committee 9 had already carried out a world-wide inquiry on the subject and was expected to report to the tenth session of the Executive Com­ mittee. It would appear that ultimately the Commission for Maritime Meteoro­ logy will draw up the plan of a warning system. In view of the present state of affairs, and while recognizing the importance of the problem~ the session agreed to postpone consideration of the matter un­ til the results of the action created by Resolution 38 (EC-IX) were known. No formal recommendation or resolution was adopted on the subject.

It noted with interest the action in South America which resulted in the establishment~ with the help of technic­ al assistance, of a regional training centre at the University of Buenos Aires. . The session was informed that the Executive Committee's Panel of Experts on meteorological developments in view of commercial jet aircraft operations, was advocating the establishment of regional training centres; however, it was agreed to postpone any decision on the subject until the Executive Com­ mittee has acted upon the report of the panel. GENERAL SUMMARY 17

It was noted that it might prove possible to expand the existing training courses in general meteorology established in Australia so as to cover high­ level forecasting techniques. In the meantime? the association agreed to adopt measures similar to those adopted by Regional Association VI in its Resolution 36 (II-RA VI) (see Re­ solution 17 (II-RA V)).

9.2 follection of re£grts on aiFcraft icing (Agenda item 9.2) The session took note of the action taken by other associations on this ques­ tion and of the comments of the International Civil Aviation Organization thereon. It was felt that the fundamental difficulty lies in the apparent impossibility of making reliable aircraft icing observations with the present techniques and procedures. Some Members are continuing experimentation on the problem of instrumentation for measuring icing. In Region V there is also a lack of an adequate number of icing reports. " In particular? the session agreed that judging from the aircraft:):'eports re­ ceived, significant aircraft icing in the Region appeared to be relatively infrequent, so that a regional scheme for studying aircraft icing in relation to various synoptic situations would very likely not have significant value. No formal resolution or recommendation was adopted on this subject.

10. CLIMATOLOGY 1O.t lmpr~~ts in the ~.!wo!.Is.§_~f clima1~1.2.9ic~~.L~.:tations (Agenda item "10.1)

10.1.1 Under this item, the session examined the problems Of reference climatological stations, of the CLIMAT message scheme, and their exchange, and of reaching regional agreement regarding the establishment of data control authorities which would be responsible for the collection, annotation and dissemination of meteorological data for various countries in the Region. "

10.1.2 The session noted the conclusion of the Commission for Climatology as con­ tained in paragraph 13 of the report of the second session of that commis­ sion concerning reference climatological stations and the support given to it by the ninth session of the Executive Committee. The majority oJ Members" of the Region have not yet been in a position to prepare a full plan for a 18 GENERAL SUMMARY network of such stations. The session therefore agreed to leave it to indi­ vidual Members to study the problems, but to ask the president of the associa­ tion to follow developments closely, in the hope that it would be practicable to develop a regional network in a reasonable time. No formal resolution was considered necessary on this subject.

10.1.3 With respect to CLIMAT and CLIMAT TEMP stations the session noted that such stations exist in th~ territories of the Members of the Region and decided ~ establish a preliminary regional network. The plan comprises a number of sta­ tions in addition to those for which CLIMAT and CLIMAT TEMP messages are al­ ready being exchanged._ The preliminary list appears as Annex'IX to the Abridg­ ed Final Report of the session. Members not included are invited to forward their lists to the Secreta~iat as soon as p6ssible for publication as an ad­ dendum. The session noted that Resolution 31 (EC-IX) requires that "all upper-­ air stations rep6rting CLIMAT TEMP data shall include CLIMAT data in the same message". In the past the value of reports included in the monthly CLIMAT TEMP broadcasts has been seriously limited by the lack of surface data without which calculati6ns 6f thickness of layers from the surface to various stan­ dard pressure levels, water vapour transport, etc., are not possible. While Resolution-31 (EC-IX) will effect some improvements it does not provide a satisfactory solution to the problem. To make full use of the CLIiVlAT TEMP data it is necessary to know the mean surface pressure, temperature and humid­ ity at the time of release of the radiosondes, instead of the daily means which are used in CLIMAT reports. The session considered that this could best be achieved by modifying the CLIMAT TEMP code FM 75 by the insertion of two additional groups containing the mean surface pressure, temperature and humid~ ity at the time of release of the radiosondes. It was decided that the presi­ dent of the association should convey the views of the session on this sub­ ject to the presidents of the Commissions for Climatology and for Synoptic Meteorology for their consideration.

10.1. 4 In regard to existing exchanges, the session had no evidence of any defici­ encies.

10.1.5 Finally, with respect to data control authorities, the session noted that all Members of the association had already established national data control authorities and that this question required no regional decision.

10.2 Hydrolog.ical observations and their exchange (Agenda item 10.2) ------~ The session agreed that no useful purpose would be served by establishing a regional plan for exchanging hydrological observations. It was not considered necessary to establish

cause of the geographical character of the Region. It was however agreed that the problem is important, and the association expressed the hope that the Ex­ ecutive Committee and Congress will pursue the proposed integration of hydro­ logy into the terms of reference of theVvorld Meteorological Organization. It was noted that in many countries of the Region, hydrology is the responsibi­ lity of agencies other than the meteorological service. No formal recommendation or resolution was adopted on this item.

10.3 .§tatio~_for_.!'~di~ti0D...!:!2~~~E}ents (Agenda' item 10.3) The session reviewed the situation in the Region in regard to radiation meas­ urements. It was noted that there is at this time no primary working standard radiation observatory in the Region. Urgent action is required to standardize instruments and to compare the different instruments in use. , The session noted that the second session of the Commission for Instruments and Methods of Observation and the ninth session of the Executive Committee had developed'various recommendations and resolutions relating to radiation observations which require consideration in the Region. It was decided that a Working Group o~ radiation measurements should be established (see Resolu­ tion 19 (II-RA V)).

10.4 Reg2:~D~.L~ct~.$.LEl2:matic_~g~.§nd-2li!!§tiE._ charts for hYErElogic~ EurE~ \ Agenda 1 tem' 10.4) Due to the unique situation in Regional Association V with respect to distribu­ tion,of ocean an~land areas, the association felt that the preparation of sub-regional and ~egional climatic atlases and climatic 9harts for hydrolo-, gical purposei:would not be practical at this time. Moreover, the effort in­ volved in the' pr,eparation of sub-regional and regional atlases might prove to be out of piopor±ion to the benefits to be derived from them. The preparation of such atlases ~ill have to be postponed for several years. In the meantime, priority should be given by Members to the preparation of national atlases. Sin:ce' :guidance is contained in Resolution 30 (EC- IX), it was not considered necessary to establish a regional 1,'lorking Group on climatic atlases, but Mem­ bers of the 11egion were urged to comply with this Executive Committee resolu­ tion. No formal recommendation' or resolution was adopted on the subject.

Recommendation 13 was taken into account when considering item 5.3. Recommendation 11 was taken into account when considering item 8.1. It was noted that the International Civil Aviation Orgahization had informed the World Meteorological Organization that the difficulties which had glven rise to Recommendation 11 have been removed and that the recommendation there­ fore required no further activation.

11.2

~egional~E~ct of)_~_Inter£l~tional~'§.2~SiE2_Ly_~ar--.l?ro.9ra!:£l~ ~ Agenda item 1l.2 .. The session noted that there appear to be n6 difficulties at the regional level in the implementation of the International Geophysical Year programme. It also considered whether any Members were encounteringdiff-iculties which might be eliminated through the assistance of other Members of the R~gion. It was noted however that the Members of the Region were assuming their res­ ponsibilities regarding the International Geophysical Year~ in so far as they were able~ and to that extent the programme is proceeding satisfactorily. No formal recommendation or resolution was adopted on this item.

11.3 l~Ehnic~~~~i~!~_progE~~ (Agenda item 11.3) The ~ession took note of the fields in which technical assistance can be provided hy the World Meteorological Organization under the United Nations' Expanded Programme of Technical Assistance; that is establishment and de­ velopment of meteorological and hydrological services; economic and tech­ nical surveys to ascertain meteorological and hydrological needs; advice in the various branches of meteorology? inCluding appropriate observing networks and the collection~ analysis and publication of data; training in all branches of meteorology and hydrology. Note was also taken of the procedures to be followed for requesting technical assistance under the normal country planning method as well as contingency financing. It was also noted that limited amounts of equipment for synoptic stations (surface and upper-air) can be provided under the Technical Assistance scheme, but that the funds available to the World Meteorological Organiza­ tion for technical assistance under the United Nations Expanded Programme are far from being sufficient to meet all requests. Even if there are im­ portant deficiencies in the regional basic synoptic network technical as­ sistance for the elimination of such deficiencies can only be provided by the World Meteorological Organization when the Member concerned. lodges a request for assistance. The session further examined whether there were any projects which could be undertaken ona regional or inter-regional basis, with the help of tech~ nical assistance. It expressed its interest 'in the plan for holding· a GE NERAL SUiVlMARY 21 seminar on hydrology in South-east Asia in co-operation between the World Meteorological Organization and the Economic Commission for Asia and the Far East. No specific request for technical assistance on a regional basis was formulated for Region V. . The question of training forecasters in the techniques for future high-level operations, by the establishment of regional trai.ning centres or holding of appropriate seminar~was taken up under item 9.1.

11.4 .

Exch~.!]ge o..Lpubli~atio!l§ (Agenda item 11.4) The session endorsed the principle of free exchange of publications? and agreed that, in order to avoid receipt by Members of publications for which they have no real requirement, it would be satisfactory to leave this ques- tion to bilateral arrangement between countries. . No recommendation or resolution was adopted on this subject.

12. BEV1'§IO~ OF IHE_B§.§OLUI.!Ol\!'§"',9F _lEE F1B§I.-2ESS10N (Agenda item 12)

Under this item· the session reconsidered the resolutj~6nsand recommendations adopted by the first session of the association in order to decide whether these resolutions should be retained or cancelled. The conclusions of the session are contained in Resolutions 2 and 20 (II-RA V).

13.2 In accordance with the decision of the Executive Committee (see paragraph 78 of the Abridged Report of the eighthsessibn of the- Executive Committee), the session decided that Resolutions 1 and 11 (II-RA V) . should be the subject of fact-finding and of implementation action with Members. 22 GENERAL SUiVlMARY

In making this choice, the session was guided by the desire to concentrate efforts on a restricted number of questions, recognized to be of fundamental importance.

13.3 With respect to fact-finding and implementati6n action in relation to Resolu­ tion 1 (II-RA V) (Recommended basic synoptic networks), the session noted that this work is already included in the normal work programme of the Secre­ tariat. With respect to fact-finding in relation to the other resolutiqns mentioned above, the session noted that this is an inherent part of the task of the association's Working Group on meteorological telecommunications. It was noted,however, in this respect, that the implementation action with Members would be carried out through the Secretary-GeneraL No forma 1 resolution was considered necessary on this' item.

15 D P~IE AND--PLAfILQF THIRD SES.§ION (Agenda item 15) The delegate of New Caledonia invited Regional Association V to hold its third session in Noumea, New Caledonia. He made it clear, however, that this invitation needed confirmation by the French Government. during the Third Congress of the World Meteorological Organization. GENERAL SUiVllViARY 23

As regards the date of the third session~ the meeting expressed a definite preference for holding it in the latter part of the Third Financial Period. In view of the difficulties that resulted for thenorld Meteorological Organi­ zation as a result of the concentration of too many sessions of constituent bodies in this very period, the session agreed, however, to take no firm de­ cision on this point.

CLOSURE OF THE SESSION

Various speakers expressed their thanks to the Philippine Government for the excellent facilities offered to the third session of Regional Association V. They emphasized the excellent spirit of co-operation of all participants in the meeting and. the efficiency of local $ecretariat arr~ngements which at all times had provided the session, without delay, wit!) the documentation requir­ ed for the deliberations. The retiring president, Mr. Casimiro del Rosario, closed the session by wish­ ing the deleg"ates "AU REVOIR". RESOLUTIONS ADOPTED BY THE SESSION

Res. 1 (II-RA V) - BASIC NETWORK OF SURFACE AND UPPER-AIR OBSERVING STATIONS FOR THE SOUTH-HEST PACIFIC REGION

THE REGIONAL ASSOCIATION FOR THE SOUTH-WEST PACIFIC,

NOTING,

(1) Resolution 2 (I-RA V), Resolution 27 (EC-VIII), the require­ ments ·for surface and upper-air synoptic observations expressed by Mem­ bers of the association (Res. 34 and 35 (58-RA V)) and by the Interna­ tional Civil Aviation Organization in Recommendations 1, 2, 4 and 9 of the MET Committee of the First Pacific Regional Air Navigation Meeting;

(2) Resolution 12 (EC-VIII) to the effect that Members are re­ quested to fill in the main gaps in the world synoptic networks)

(3) Resolution 8 (CAe-II) which establishes the priority which should be given to radio and radar-wind observations over radiosonde observations in tropical areas;

RECOM1\tIENDS that the International Civil Aviation Organization be informed of the following meteorological requirements for Regional As­ sociation V in regard to routine air reporting and be requested to take them into account·~

(1) As regards frequency of observations, existing international procedures applicable to conventional aircraft operations as well as regional supplementary:procedures in Regional Association V are consider­ ed adequate. Any reduction in the frequency of observation and report= 1ng would be detrimental to the meteorological service to be provided for these operations;

(2) With respect to 'high-speed/high-flying aircraft~ the fre­ quency of air reporting by aircraft with a true air speed exceeding 325 knots should be such that the distance between the points at which two successive observations are made, does not exceed 500 nautical miles. Reports should comprise at least temperature; wind speed and direction~ D=value and significant weather; (3) The concept of an exemption procedure which will permit the meteorological sery~ces to exempt c;.er'tain airc:r,~U from transmitting ro"ut{ne·weather· reports in order to avoid redundancy in reporting is . acceptable in pril)c~ple provided that the application of the procedure is the responsibility of the meteorological office at the point of'-de- parture; ,.

RESERVATIONS ON RESOLUTION 1 (U-RA V)

1. Presented by the delegatibn of New Caledonia -----,--'-~----- ...... ---'---..----- New Caledonia c9nnot, 'under present circumstances, "(;le itself down to the full implementation of the measures to be a'dopted under 'Resolution L This applies particularly to night observations at stations in its network.

French Polyne$ia wishes to submH a reservation with respect to the, iinplementation of the 'recommended observation programme in 'its territory. Surface and upper-air observations are not carried out at 0900, 1200 and 1500 GMT, and at the moment it is impossible to give a date when these obs~rvations will be made.

The Philippines reserves its position on the requirement of upper-air information from Manila. We agree to leaving it in the plan but we believe that this requirement is currently being met by the avaiiabiIity of similar data from Clark Field (98327) plus pilot balloon observations from Sang ley Pt (98424).

British Borneo reserves its position regarding the implementation of the radiosonde-rawin station at Labuna (96465).

The Australian delegation desires to reserve its position concerning the pilot balloon observations for 1200 and 1800 GMT at Nomote (94044), Halls Creek (94212) and Christmas Island (96995) and, also, the radiowind observa­ tion for 1200 GMT at Hacquarie Island (94998).

The ,wishes to reserve its position regarding the imple­ mentation of radiosonde observations at Funafuti (91643) and of radiosonde- ANNEX II 63

radiowind observations at Tarawa (91610) and at Fanning Island (91487) or Christmas Island (91490) and of surface and pilot balloon observations at Flint Island (91XXX).

New Zealand wishes to reserve its position regarding the implementa­ tion of radiosonde observations at Rarotonga (91843) and of radiowind obser­ vations at Raoul Island (91997), Campbell Island (93944) and Chatham Island (93986).

The United l(ingdom and New Zealand vIish to reserve their position re~ garding the implementation of surface reports at 0900 and 1500 GMT at all stations under their respective control and which are listed for this re­ quirement until such time as a specific demand from these reports has been .. ,.established.•.

1.1 Pending a definite recommendation by the CCIR, the difference between the frequencies associated with the marking and spacing elements should be 800 c/s. The value of the frequency shift should be maintained within 3 per cent of its nominal value, i.e. 400 c/s ± 3 per cent. Not e s (a) This conforms to the CCIR preferred value of 400 c/s for the frequency shift associated with systems operating between 3 mc/s and 30mc/s and working on only two conditions (see CCIR, Plenary Assembly VIII? Re­ commendation No. 150). ( b) This is also in line with the suggestion that the difference between the black and white frequencies for facsimile systems employing a similar type of modulation should be 800 c/s.

1.2 Pending a definite recommendation by the CCIR, the radio frequency associated with the marking element be higher than that associated with the spacing element.

Not e s (a) This specification conforms to the present standard adopted by ICAO. (b) The definitions of "marking" and IIspacing" are those contained in the CCIT List of Essential Telecommunication Terms (Yellow Book) - i.e. the "marking" signal corresponds to the IIstop" element.

1.3 The standard modulation rate be 50 bauds.

1.4 The nominal duration of the transmitting cycle be at least 7.4 units

(preferably 7 0 5) the stop element lasting for at least 1.4 units (preferably 1.5) •

10 5 The International Telegraph Alphabet No.2 be used. ANNEX VI 75

1.6 The maximum number of characters which the textual line of page print- ing apparatus may contain should i:>e fixed at 69.

1.7 That where it is not possible to adherB to these specifications, characteristics be agreed bilaterally or multi-laterally between the services concerned and detailed characteristics be published in appropriate publica= tions or documents for the information of all concerned.

1.8 That Members should ensure that adequate liaison exists between their meteorological telecommunications services and their telecommunications au­ thorities and also where practicable with any firms producing telecommunica­ tions equipment.

2~ TELECOMMUNICATION PROCEDURES

2.1 Call signals - A radio-teleprinter broadcast will be preceded by the transmission of call signals.

201.1 From call signals - The call signals will comprise ~ the general call to all stations ( transmitted three times), the conventional signal DE, the identification of the broadcasting station consisting of the radio call sign followed by the frequency reference index or indices (transmitted three times) and the letters RY repeated without separation for one line. E x amp 1 e .. CQ CQ. CQ . DE . WSY 21/22 . . WSY 21/22 ¥JSY 21/22 .... . RYRYRY RYRYRYRYRYRYRYRYRYRYRYRYRYRY RYRYRY RY RYRYRYRYRYRY RY RYRYRYRY RYRY RY RYRYRY . . ~ .

2.1.2 ~mi~on of call sl~~a'l~ .. Call signals will be transmitted (a) before broadcasts due to begin at a fixed time for 5.'niinu:t:~§ which precede the official time of siarting; (b) each time that the station has 'no traffic' during assigned broadcast periods? (c) during the 5 minutes preceding the first broadcast following a change of frequency on the frequency in which the broadcast will take place.

2.2 The order of the transmission sha~l be according to paragraph 1 of Part B,-Chapter I, Volume C of i.'JNIO publication No.9. TP.4. In the event of interruption of radio-teleprinter messages for any cause, the broadcast sche­ dule should be maintained on resumption of emissions, and the messages which have not been already broadcast should be broadcast as time becomes available in the allocated time-division periods in the reverse order of their time of receipt at the subcontinental broadcasting station. 76 ANNEX VI

2.3.1 In radio-teleprinter exchanges where a communication centre is respons­ ible for the relay of the bulletins originated by another centre, the abbre­ viated heading must not be altered whether the bulletin is re-transmitted com­ plete or incomplete; 2.3.2 Where a bulletin is received with some groups of individual reports garbled~ the relay centre shall retransmit the bulletin as received and if possible obtain a retransmission from the originating centre; 2.3.3 National instructions shall cover the case of the measures to be taken when complete' garbling occurs in order to ensure that all usable data are relayed with a minimum delay~ with the elimination, where possible, of com­ pletely garbled portions;

2 0 3.4 Whenever the elimination mentioned above is performed~ the abbrevia­ tion 'INC' shall be added at the end, to indicate that the bulletin is incom­ plete;

2 0 3.5 The relay centre shall take all necessary steps to receive from the originating centre those parts of the bulletin which were garbled, and trans­ mit them as soon as possible.

2.4.1 Inclusion of ships ' call signs, handling of plain language radio-tele­ phony in flight'reports"date and time group, abbreviated headings, good qua­ lity of meteorological transmissions, notification of changes, shall be ac­ cording to Part B of WMO publication No. 9.TP.4.

2.4.2 The texts must be perfectly presented and rigorously checked, and ne­ cessary corrections ought to be made before transmission. When an error is de­ tected and cannot be otherwise corrected, a correction shall be transmitted at the end of the iJroadcast immediately preceding the word "END". The letters "COR" shall be used to indicate a correction. Schedules shall not be prolonged to effect corrections beyond the next transmission schedule. 77
