WORLD METEOROLOGICAL ORGANIZATION

OCTOBER 1964 VOL.XIII N0.4 THE WORLD METEOROLOGICAL ORGANIZATION (WMO) is a specialized agency of the of which 124 States and Territories are Members It was created : - to facilitate international co-operation in the establishment of networks of stations and centres to provide meteorological services and observations to promote the establishment and maintenance of systems for the rapid exchange of meteorological information - to promote standardization of meteorological observations and ensure the uniform publication of observations and statistics to further the application of meteorology to aviation, shipping, agriculture and other human activities to encourage research and training in meteorology The World Meteorological Congress is the supreme body of the Organization. It brings together the delegates of all Members once every four years to determine general policies for the fulfilment of the purposes of the Organization The Executive Committee is composed of 21 directors of national meteorological services, and meets at least once a year to supervise the programme approved by Congress Six Regional Associations are each composed of Members whose task is to co-ordinate meteorological activities within their respective regions Eight Technical Commissions composed of experts designated by Members, are responsible for studying the special technical branches relating to meteorological observation, analysis, forecasting, research and the applications of meteorology

H. H. (Compiler)- Meteorological Meteorological Glossary Glossary ...... 123 123 RADIOACTIVITY in the upper air measured by the VAISALA RADIOACTIVITY SON DE, TYPE NS 11

The Radioactivity Sonde is a radiosonde-type detector for measuring radioactive radiation in the upper air. The instrument is intended to be launch­ ed like an ordinary radiosonde, attached to a meteorological sounding balloon which is inflated with hydrogen or helium. The maximum height Dimensions (cover box) : which can be reached depends upon the size and 10 X 15 X 22 cm (4 X 6 X 8 Inch) Weight (incl. battery, antenna, quality of the balloon. Heights up to 40,000 metres hanger, parachute (130,000 ft) are within capability of present meteor­ and suspension stri~~) : approx. 1200 grams (2\12 lb) ological balloons.

The signals from the sonde are received and recorded at a ground station by means of a special receiver: RADIOACTIVITY SONDE GROUND SET, TYPE NR 11

The receiver is equipped with an au­ tomatic paper recorder for graphical representation of the radiation, and a digital counter for numerical display. An external counter or tape recorder can also be used. The paper recorder functions as a rate meter, indicating directly the mean pulse frequency as a function of time. The pulse frequency readings are directly readable in mR/h. One operator only Is needed for per­ forming a radiation observation, and the results are Immediately available after the recording.

HELLFAX-Weather Chart Recorder Type BS 110 MD Partial view of the Meteorological Office, Bangkok

HELLFAX Continuous Recorders are most economical in use ; they record weather charts broadcast by facsimile on dry unsensitized white paper. Climatic conditions such as frost, heat, extreme humidity or aridity have no influence on the quality of the recording.

HELLFAX equipment is reliable and easy to operate. A built-in device at the recorder provides for remote setting of index and r.p.m. by the transmitter; thus fully automatic reception is now possible.

model model VT VT 145 145 AUSTRALIA' RADAR ,WEATHERM In April, 1964, the Commonwealth Bureau of Meteorology, Melbourne, Aus­ tralia, installed the very latest in radar weather equipment in the University of Melbourne. This equipment consists of a 10 cm wavelength primary radar transmitter and receiver and has a paraboloid antenna that rises high from the roof of one of the campus' tall buildings. Control and display facilities are located at both the university and at the Bureau of Meteorology's Victoria Divisional office, four cable miles away, where technicians can operate the radar by communications facilities and remote control. Video and synchronizing signals pulse along telephone cables and coaxial cables from the university to the divisional office. The main characteristics of this weather radar are: Transmitter frequency 2800 MC/S peak pulse power 600 KW pulse length (switchable) 0.5 micro sec., 2 micro sec. pulse repetition 310 pps Receiver noise figure 3 dB with parametric amplifier Antenna type parabolic reflector diameter 3m Range limit max. 200 nautical miles ~\~MO~ Height limit max. 60,000 feet (t:)~·-. ·r<)\1' !':'!!!!e~!~b~h~~nki~~.~~!~~i~oky~~~!2!1~IJT2~ ~
