16. Abstract
This document's primary purpose is to provide the means for locating and extracting GEOS-3 altimeter data acquired for the analysis of specific hurricanes, tropical storms and other disturbances. This data is also expected to be extremely useful in the analysis of the behavior of the altimeter instrument in the presence of severe meteorological disturbances as well as provide a data base which can be useful in the resolution of apparently anomalous geoid or sea surface characteristics. Geographic locations of 1975 hurricanes and other tropical disturbances have been correlated with the closest approaching orbits of the GEOS-3 satellite and its radar altimeter. The disturbance locations and altimeter data were gathered for a seven-month period beginning with GEOS-3 launch in mid-April 1975. Areas of coverage were the Atlantic Ocean, the Carribean, the Gulf of Mexico, the west coast of the continental United States, and the central and western Pacific Ocean. Volume I contains disturbance coverage data for the Atlantic Ocean, Gulf of Mexico, and Eastern Pacific Ocean. Central and Western Pacific coverage is documented in Volume II.

4.1 General Much of the data on the storms occurring in these areas were extracted from Tropical Disturbance Classification Worksheets. Since the coding system used was not clearly understood by the preparer of this document (no accompanying legend or definitions were provided) and the sheets not readable in some places, the information contained in this section is incomplete as presented. Therefore, it was decided to include all of the worksheets. in Appendix-A, for reference purposes. Storms as identified on the worksheets are listed below together with their periods of occurrence. Tropical Disturbance (TD-02) (4/19/75-4/28/75) Tropical Disturbance (No Name-A) (7/21/75-7/25/75) "Mamie" (TD-03) (7/26/75-7/30/75) "Nina" (TD-04) (7/31/75-8/4/75) Tropical Disturbance (TD-05) (8/4/75-8/6/75) "Ora" (TD-06) (8/9/75-8/12/75) "Phyllis" (TD-07) (8/12/75-8/17/75) Storm No Name-B (8/13/75-8/16/75) "Rita" (TD-08) (8/16/75-8/23/75) "Susan" (TD-09) .(8/24/75-9/1/75) "Tess" (TD-IO) (8/31/75-9/9/75) "Viola" (TD-I) (9/4/75-9/8/75) "Winnie" (TD-12) (9/7/75-9/12/75) "Alice"- (TD-13) (9/15/75-9/20/75) "Betty" (TD-14) (9/16/75-9/23/75) "Cora" (TD-15) (10/l/75-10/6/75) "Doris" (TD-16) (10/3/75-10/6/75) "Elsie" (TD-17) (10/9/75-10/15/75) Tropical Disturbance (T0-18) (10/14/75-10/20/75) "Flossie" (TD-19) (10/20/75-10/23/75)
4.1-1 Table 4-1 is a complete listing of all tropical cyclones occurring in the Pacific Area during the calendar year 1975, with the exception of Typhoon Lola (Storm #01) which occurred several months prior to GEOS-3 launch. Several other storms, not included on the above list, are included in Table 4-1. These are: Typhoons Ida and June, Tropical Storms Grace and Helen, and two tropical depressions (TD24 and TD25). Table 4-I contains information of general interest concerning these storms including storm number, type, name (if assigned one), period of warning, maximum wind velocity, minimum pressure (SLP), etc. Detailed meteorological information has also been made available for certain of the Pacific-storms and is included in this document. Meteoro logical summaries are provided for the following: Typhoon "Lola" Typhoon "Nina" Typhoon "Ora" Typhoon "Phyllis" Typhoon "Rita" Typhoon "Tess" Typhoon "Winnie" Typhoon "Alice" Typhoon "Betty" Typhoon "Cora" Typhoon "Elsie" Typhoon "Flossie" Typhoon "Ida" Typhoon "June"
In the cases of Ida, June, Grace, Helen, TD24, and TD25, no detailed information concerning their day-to-day locations was provided. However, general track maps were provided. Therefore, these maps were used to estimate the positions of these storms.

(July 31 - August 4, 1975)
Meteorological History/Data
As Tropical Storm Mamie dissipated and drifted toward Korea, the monsoon trough migrated northward leaving a well-defined trough line extending south eastward from the remains of Mamie into the Philippine Sea. A tropical disturbance spawned in this trough near 20N 137E on 29 July and rapidly developed into Typhoon Nina, one of the most destructive storms of the 1975 season. After initial detection by satellite and classification as a tropical disturbance, TD-04 moved southwestward for approximately 36 hours as surface and upper-air circulations became organized and vertically aligned. By 1200Z on the 31st the system slowed, intensified rapidly to tropical storm strength, and began turning to the northwest. As the storm made this turn, it responded to midtropospheric steering flow and accelerated along the equatorward periphery of the 500 mb subtropical ridge. Continued building of the subtropical ridge to the west forced Nina to take a west-northwesterly track toward Taiwan just prior to reaching typhoon intensity on 1 August. Nina underwent explosive deepening late on 1 August. Aircraft recon naissance data indicated a 63 mb drop in sea level pressure at the typhoon center between August 1 at 1437Z and August 2 at 0830Z, with maximum surface winds increasing from 65 knots to 130 knots during that period. A peak intensity of 135 knots was attained on the 2nd at 1200Z, approximately 200nm east of Taiwan. The typhoon slowly decreased in intensity while approaching the island,.making landfall near the coastal city of Hualien on the 3rd at 0300Z with maximum surface winds of 100 kt. Nina ehtered the Formosa Straits with minimal typhoon strength, and *weakeied to apprdximately 60 knots before striking the China mainland on the 3rd at 150OZ. Nina moved inland and lost tropical cyclone characteristics on the 4th of August.
Damage/Deaths Much of the typhoon's strength was lost as it battered across Taiwan's central mountain range, fortunately sparing the most populous areas from the more intensive winds near the eye. Nevertheless, Nina's trek across Taiwain reportedly left 25 people dead, 4 missing and 168 injured. It was also reported that over 3,000 homes were at least partially collapsed, 39 fishing boats were sunk, anda 16,000 ton Korean freighter, THE SUN STAR, was capsized near Koahsiung harbor. Damage from flooding and landslides was.widespread.

Qo-z~~l a5-sm)a;)-SIE 10~~1f 1767673 Z 07( ) TYPHOON ORA
(August 9 - August 12, 1976)
Meteorological History/Data
The third typhoon of the season, Ora, was small and short lived. Ora first appeared as a weak circulation in the near equatorial trough (drawn north by the influence of Typhoon Nina and TD-05) during the evening of the 8th. During the next 30 hours, this weak circulation moved northwestward at 6 knots showing little intensification.
On the morning of the 10th, a rapidly moving upper-level trough in the midlatitude westerlies was located to the northwest of the circulation. This trough provided a highly efficient high altitude outflow channel which allowed Ora to grow from a tropical depression into a typhoon within 30 hours. As this trough moved .quickly toward the east, Ora responded with a north northeastward movement. When Ora's eye passed over Miyako Jima at 0600Z on the l1th, the weather stations recorded 6-knot surface winds and a minimum pressure of 976 MB. Simultaneously, a ship (JL 11) 120 nm to the east reported 55-knot sustained winds. At 0749Z on the l1th, 50-knot gusts were recorded at Kadena AB, Okinawa, 150nm northeast of Ora. As the trough passed to the east, the subtropical high over central China built rapidly eastward and Ora shifted northwestward and accelerated to 15 knots. By the morning of the 12th, Ora had turned westward at 13 knots until landfall was made on the 12that 080OZ near Yung-chia on the central China coast.
From OOOOZ on the l1th, until striking the China coast, Ora maintained -typhoon strength winds of 65 knots. A surface high pressure cell moving east ward from the sea of Japan into the North Pacific rendered Ora a highly asynnmetric storm with 30-knot winds extending 300 nm to the northeast and only 150 nm to the southwest.
.Damage Estimates: Although little destruction was directly attributed to Ora, monsoon rains were spawned over the Philippines and caused widespread flooding and landslides. Choppy waters near Tocloban, Leyte capsized a crowded motorboat leaving 15 dead and 30 missing.

(August 12 - August 17, 1975)
Meteorological History/Data
Since,early August, a monsoon trough had extended from the remains of Typhoon Nina in central China to an area west of Guam. A number of surface circulations appeared in this trough as early as the 8th of August, but it was not until the morning of the l1th that Phyllis first appeared as a tropical disturbance from 380 nm west-southwest of Guam. The first warning on,what was to become the fourth typhoon of 1975, was issued on the morning of the 12th. Aircraft reconnaissance located TD-07 395 nm west-southwest of Guam with center winds of 30 knots. At 0600Z on the 12th, the depression was upgraded to a 35-knot tropical storm. Aircraft reported multiple surface centers and a weak and diffuse 700 mb center.
Initially, the upper-level anticyc-lone was located 110 nm west of the surface center. However, by the morning of the 13th the upper and lower levels had become vertical. On the 13th at 0833Z, aircraft reported a closed wall cloud with an eye 30 nm in diameter. A Russian research vessel (EREC)L reported 60-knot surface winds 60 nm west-southwest ,of Phyllis at 1200Z on the 13th; thus, Phyllis was upgraded to typhoon with maximum winds of 70 knots.
By the 13th, the mid-tropospheric ridge over China began to weaken while the ridge east of Japan intensified. Twenty-four hours later, Phyllis' forward speed had increased to 18 knots. The typhoon attained a maximum intensity of 120 knots on the 14th at 1800Z after aircraft had recorded a minimum sea level pressure of 920 mb at 1505Z. By the 15th, Phyllis' move ment had slowed-to 7 knots and had become northwestward as the midtropospheric ridge built westward across Japan. After turning to the northwest, Phyllis once again accelerated, and by the afternoon of the 16th, was located 165 nm southeast of the Japanese Island of Shikoku. As Phyllis approached Japan, Shimizu (WMO station 47898, elev 99 ft), recorded sustained surface winds of 77 knots on the 16th at 1800Z and a minimum pressure of 970 mb at 2300Z. Murotomisaki (WMO station 47899, elev 606 ft:), recorded sustained surface winds of 73 knots at 2000Z on the 16th. Phyllis, with 80-knot sustained winds, made landfall during the morning of the 17th near the southwestern edge of Shikoku.
Damage Estimates/Loss of Life
In her wake Phyllis left extensive damage and loss of life. On Shikoku alone there were at least 60 dead, 146 injured, and 12 missing due to the combination of heavy rains, flooding and numerous landslides. At least 489 houses were reported collapsed, 577 damaged, 58 washed away and thousands inundated. Phyllis passed 20 nm to the west of Iwakuni MCAS which reported maximum gusts of 38 knots.

(August 16 - August 23, 1975)
Meteorological History/Data
The third typhoon in August, Rita, made landfall in Japan closely following the wake of Typhoon Phyllis. Due to heavy rains brought by Rita, the storm proved to be the most damaging to affect the northern Japanese islands since 1965.
The typhoon's birth can be traced to the development of a monsoon depres sion some 180 nm southeast of Iknawa on the 18th. Drifting first east then westward, Rita began to gain strength as aircraft reconnaissance reports verified storm force winds in the circulation on the following day. Due to a weakening subtropical high cell east of'Japan, heights began to fall north of Rita. In response, the storm reversed track to an easterly direction a few miles off the northern tip of Okinawa. A minimum pressure of 983.4 mb was registered at Kadena Air Base on the 20th at 0620Z although winds were comparatively light with a peak gust of 37 knots from the northwest recorded at 0514Z.
An approaching short wave over Manchuria began to draw Rita on a more northward course late on the 20th. By the afternoon of the 21st, typhoon force winds were reached and Rita's circulation had grown significantly in size. Due to the building pressure gradient associated with the high cell east of Japan, gale force winds extended some 300 nm in the typhoon's eastern semicircle. As the short wave continued to approach the typhoon, Rita accel erated gradually in a north-northeasterly direction, making landfall 30 nm west of Osaka late on the 22nd. Prior to landfall, Rita's 40-60 nm diameter eye passed-over Murotomisaki (WMO station 47899, .elev 606 ft), Shikoku. The station experienced'a pressure reading of 966.3 mb at 1200Z and sustained surface winds of 80 knots. Quickly crossing central Honshu, Rita veered slightly and accelerated to speeds of 30-35 knots ahead of an advancing cold front in the Sea of Japan. First tracking along the western coast, Rita crossed the northern portion of Honshu, finally emerging back into the Pacific on a northeasterly heading. Strong gusty winds occurred along the exposed southern coast of Honshu between the Kii and Boso peninsulas. Southerly winds gusting near 55 knots were recorded.at Yokota Air Base between 0300Z and 0400Z on the 23rd. Merging with the frontal zone south of Hokkaido, Rita continued to track northeastward as an extratropical low.
Damage Estimates/Loss of Life
Torrential rains swept Hokkaido with amounts totaling near 8.2 inches in 24 hours. Landslides and flash flooding as a result of the rains were respon sible for extensive crop and property damage with farmlands inundated and 36,000 houses flooded throughout Japan. At least 26 deaths were attributed to the typhoon. Newspaper reports indicate that it was the worst flooding in 10 years for Hokkaido. Several major rivers on the island overflowed their banks leaving towns marooned and isolated.

Meteorological History/Data Satellite data on the evening of 31 August first showed preliminary upper-level features indicative of a formative outflow pattern. Divergent flow on the southern side of the persistent tropical upper tropospheric trough was enhancing the tropical cyclone formation process and-a closed surface circulation was analyzed in the same area the following morning, 600 nm east-northeast of Saipan. Midtropospheric ridging frdm Japan to the Dateline initially caused Tess' embryo to drift west-southwest. As this ridge weakened, the system began tracking West-northwest, develoDinq slowly. As the trough migrated toward the north, an. anticyclone .was established over the surface circulation, which was now located 280 nm east of Pagan Island in the northern Mariana Islands. The first warning on Tess was issued on the morning of 2 September after reconnaissance aircraft and satellite data indicated rapid development. Tess was upgraded to a typhoon on the 3rd at 1200Z when reconnaissance aircraft reported surface winds of 75 knots approximately 250 nm west of the Maug Islands. The typhoon was now moving ina more northerly direction toward-a weakness-in the collapsing midtropospheric ridge to the north. Thirty hours later on the 4th at 1800Z, Tess reached a minimum central pressure of 945 mb and maximum sustained surface winds of 95 knots. Tropical Storm.Viola had.formed approximately 1200 nm southwest of Tess on the 4th and subsequently moved within 900 nm of Tess before dissipating on the 7thU Viola's 'presence helps explain Tess' reduced speed of movement and irregular track during this period. On the 7th at OoaZ, the SS OREGON reported estimated surface winds of 65 knots while 60 nm east-southeast of the storm's center. Tess maintained typhoon intensity until the 8th at 1800Z, when it-moved into a hostile environment of colder water and began interacting with an approaching frontal system. Satellite data indicated that the typhoon-was becoming extratropical, and by the morning of the 10th .Tess had merged intd the frontal system. Damage Estimates The entire life time of Tess was spent between 153E and 145E, an-area of the -western North Pacific having few populated is-lands. This system did little if any damage during its ten day lifespan.

Meteorological History/Data Winnie was first detected by satellite on 5 September as a weak tropical disturbance approximately 300 nm northwest of Wake Island. At this time Typhoon Tess was approximately 900 nm to the northwest of Winnie with a surface trough extending southeastward to Wake Island. The combination of surface troughing-and a favorable upper air pattern allowed this disturbance to develop. The first warning was issued early on the morning of the 9th based on satellite data. From her initial detection as a disturbance, Winnie moved slowly north northeastward, attaining minimal tropical storm intensity at 2100Z on the 8th. The storm was now 400 nm north-northwest of Wake Island andposed no signifi cant threat to any inhabited islands. From the time of initial tropical storm strength until 120OZ on the llth, Winnie was steered on a northerly course by the combination of a sharp mid tropospheric trough to the west and a blocking ridge to the east. A 200-mb trough extending to the west of Winnie inhibited development past minimal typhoon strength with typhoon force winds persisting only for a 24-hour period from,1800Z on the 9th to 1800- on the 10th. -A Japanese ship (JEEU), located approximately 35 nm north of Winnie, reported sustained winds of 65 knots at-180OZ on the 9th. - -Approaching a frontal system near 35N, Winnie came under stronger steering flow, accelerated to near 20 knots, and began to weaken. A short wave trough moving.through'the'long wave ridge.dmtinished its--amplitude and-Winnie assumed a more northeasterly track while continuing to accelerate. By COOOZ on the S12th, Winnie was absorbed into the frontal system and became an extratropical system with maximum winds of 30 knots. Damage Estimates Although no threat to inhabited islands, Winnie did represent a threat -to shipping. It,in fact, sank a 44-foot sailboat, THE FLATBUSH MAN, on a pleasure cruise from Marcus Island to Hawaii. The four people aboard were adrift for 13 days ina rubber raft until 21 September when a-Russian whaling vessel picked them up.

(September 15 - September 20, 1975)
Meteorological -History/Data
On 11 September, a tropical upper tropospheric trough extended westward across the-western North Pacific into the South China Sea with several cyclonic cells apparent along the trough axis. On the morning of the 12th, a tropical disturbance was identified on satellite data to the south of the trough, near 12N, 148E. Outflow weakened'over the disturbance as the trough moved to the northwest; this rendered upper-level divergence insufficient to induce a surface vortex and stimulate further development. The anticyclone drifted westward with little apparent change until the 15th, when it moved over a small vortex in the monsoon trough near 13N 131E. As this upper-level anti cyclone became vertically-aligned over the surface cyclone, the system under went rapid tropical cyclone development. This system became Tropical Storm Alice on the afternoon of the 16th and intensified to typhoon strength within 24 hours. On the 17th at 1430Z, air craft reconnaissance data indicated a 32-mb drop in central pressure during the previous 21 hours and maximum flight level winds of 105 knots were recorded on this eye penetration. Reduced inflow resulting from the development of Typhoon Betty (1200 nm to the east) inhibited further development as Alice approached central Luzon. At 2000Z on the 17th, the typhoon made landfall near Casiguran, Luzon with maximum surface winds of 75 knots. Alice passed Luzon near 16N, and entered the South China Sea at 0400Z on the 18th with surface winds of 65 knots. Wallace Air Station reported winds of 40 knots with gusts to 60 knots at-0129Z; a peak gust of 42 knots was recorded at Baguio'at 0432A. No significant damage was reported during the Luzon crossing.
Alice continued to a west-northwest track across the South China Sea in
- response to moderate steering flow along the southern periphery of the 500 mb subtropical ridge. Maximum surface winds decreased to 60 knots at 1200Z on the 18th and Alice maintained that intensity until just prior to striking the 1lainan coast at 1800Z on. the 19th. Alice was still well-organized as she -entered the Gulf of Tonkin with 50-knot winds, but weakened rapidly thereafter and dissipated upon movinginland over North Vietnam.
Damage,Estimates
No significant damage was reported.

(Septemb6r 16 - Se'ptember 23, 1976)
Meteorological History/Data
As Typhoon Alice approached the Philippine Islands on the 16th of September, another tropical circulation was detected in the monsoonal trough some 200 nm south of Guam. Moving northward at nearly 20 knots, this distur bance passed within 50 nm of Guam early on the 17th. By the afternoon of the 17th the circulation, now TD-14, turned sharply to the west as it approached the southern periphery of the subtropical ridge. TD-14-attained tropical storm intensity on the morning of the 18th while moving westward at 12 knots. The subtropical ridge to the west of Tropical Storm Betty was weakened by a series of middle tropospheric short wave troughs. This produced weak steering currents for the storm and the westward movement slowed to 5 knots. By the 19th, the subtropical ridge, influenced by Typhoon Alice, intensified and receded to the north. In response, Betty began moving northwestward and accelerated to 13 knots.
On the 19th, as a weak upper tropospheric trough to the west deepened, and created a highly efficient outflow channel to the mid-latitude westerlies, Betty began to intensify. By the 20th, Alice had weakened, allowing the subtropical ridge northwest of Betty to build southward. Betty again responded by moving westward. At 0230Z on the 22nd, Typhoon Betty attained a maximum intensity of 95 knots as reconnaissance aircraft recorded a minimum sea-level pressure of 944 mb. The outflow channel to the north (evident on the 19th) was severed by the 21st, but by then Betty had established an outflow channel to the upper tropospheric monsoon easterlies to the south; thus, Betty continued to intensify until the 22nd.
At 1200Z on the 21st, a ship located 140 nm northeast of the storm esti mated winds at 55 knots and seas of 27 feet. The 22 September OOOOZ rawinsonde at Ishagakishima (110 nm NNE of Betty) showed 70-knot winds from the 3,000 foot through the 18,000 foot level.
The typhoon, when some 120 nm from Taiwan, was placed under constant surveillance by the radar at Hualien, Taiwan. Upon reaching Taiwan, Betty began to weaken. The typhoon's track became west-northwestward as the storm interacted with a lee-side trough created by the high mountain ranges on Taiwan. Containing winds near 80 knots, Betty crossed into southern Taiwan about 15 nm north of Taitung.
After crossing the mountains of southern Taiwan, the storm's track became west-southwestward. Weakened by the rugged terrain, Betty entered the Taiwan Strait as a minimal typhoon. It continued to weaken and crossed the Chinese coast on the evening of the 23rd with 50-knot winds. By the 24th, Betty had degenerated into a low pressure area some 100 nm north of Hong Kong.
,4,16.-1 Damage Estimates/Loss of Life
Unofficial reports indicated 12 dead, scores injured, and hundreds homeless in the typhoon's wake. Nearly a thousand tourists were stranded as mud slides covered highways. In addition, more than 200 homes were leveled and hundreds of others damaged.

Meteorological History/Data
Weak troughing in the low level easterlies spawned a disturbance near ION,-142E on the morning of 29 September, as indicated by satellite and synoptic data. This disturbance drifted west-northwest for the next several days; on 1 October, aircraft reconnaissance reported surface winds of 30 knots.
For the next 24 hours, the 700 mb center was displaced as much as 24 nm to the northwest of the large and diffuse surface center. This center had a diameter as large as 80 nm with weak temperature and pressure gradients, and correspondingly light winds. From initial detection until the evening of the 3rd, development of a good outflow channel to the west and northwest was restricted by an upper tropospheric trough to the west. Despite this lack of outflow, the storm continued to develop. Cora was upgraded to typhoon strength on the 3rd when aircraft reconnaissance reported 70-knot surface winds and a closed wall cloud. The system continued to lack good vertical structure through the evening of the 3rd when the 700 mb center was still displaced east of the surface center.
For the first 48 hours, Cora was situated between two large high pressure cells and moved toward the northwest at 13 knots. On the 3rd, the high pressure cell north of Taiwan began to weaken rapidly and collapsed. Strong ridging was now building to the east of Cora. At this time, Cora began to slow down prior to a gradual recurvature near 25N.
As Cora passed 100 nm to the east of Okinawa on the morning of the 4th, Kadena AB recorded a peak gust of 31 knots. The system now began a gradual acceleration as it entered an area of strong westerlies to the northeast of the high pressure cell. That evening Cora attained a minimum central pressure of 943 mb and maximum sustainedsurface winds of 105 knots. Both satellite and synoptic data indicated excellent outflow in all quadrants except the northwest where a minor trough was still restricting the outflow.
By the morning of the 5th, satellite and synoptic data indicated that the primary upper-level outflow was not confined to the north-northeast. Although Cora was in an area of strong vertical shear, typhoon strength winds were still maintained for the next 24 hours. Moving to the northeast at 30 knots, the typhoon continued to come into increasingly strong westerly steering flow. Cora passed 120 nm south-southeast of Tokyo on the evening of the 5th.
Satellite data on the 6th indicated that there was very little upper level outflow, but an apparent low-level circulation was still visible. The remains of Cora were now moving to the east at 40 knots as an extratropical system with surface winds of 55 knots.

______/5_ I 3b44 0- 'I? TYPHOON ELSIE (October 8 - October 15, 1975)
Meteorological History/Data
By the 6th of October, the monsoonal trough had become quite active and was oriented east-west along 8N from the Philippines to 160E. Typhoon Elsie developed in this trough with a well-defined surface circulation located approximately 250 nm southwest of Guam on the 8th. The first warning was issued on the morning of the 9th and Elsie attained typhoon strength 48 hours later. At this point, Elsie began slowing down as the storm approached the western extent of the mid-tropospheric subtropical ridge. Elsie then underwent explosive deepening and aircraft reconnaissance recorded a 69 mb drop in the central pressure at the typhoon center between the 102052Z and I1430Z fixes. The maximum surface winds increased from 65 knots to 135 knots during this period. As Elsie approached the Bashi Channel, Basco, in the Bataan Islands (WMO station 98135, elev 184 ft), 40 nm east of Elsie's center, reported maximum sustained winds of 65 knots. Elsie continued moving west-northwest through the Bataan Islands on the 12th. As the subtropical ridge then built westward, Elsie began a more westerly track into the South China Sea. As the typhoon entered the South China Sea, it began to weaken with inflow restri'cted to the north by the Asian continent. Still, the Royal Observatory, Hong Kong, reported that typhoon Elsie was one of the most intense typhoons ever to affect Hong Kong in the month of October. Royal Observatory radar began tracking the storm by late afternoon on the 13th and Elsie passed 35 nm to the south of Hong Kong on the 14th. At that time the maximum sustained winds recorded at Hong Kong were 70 knots with gusts up to 118 knots. The lowest pressure recorded in Hong Kong was 987.5 mb.
After passing south of Hong Kong, Elsie continued westward, making land fall on the southern China coast at approximately 1500Z on the 14th. Elsie then dissipated rapidly over the Asian mainland.
Damage Estimates Fortunately, the maximum winds occured at a low tide, thus reducing flooding. Seven ocean-going vessels drifted from their moorings and one small craft and a fishing junk capsized. There were no fatalities reported, but 46 people were injured by flying debris.

(October 20 - October 23, 1975)
Meteorological History/Data
*The circulation which was to become typhoon Flossie was first analyzed 500 nm west-southwest of Guam on the OOOOZ surface analysis of 14 October. This disturbance, apparently initiated by an upper tropospheric cyclone, then began drifting west. Its development was somewhat retarded on the 15th and 16th by the presence of TD-18, a disturbance 420 nm to the north-northeast. On the 19th, the disturbance (Flossie) moved into the South China Sea after crossing Luzon and began to intensify.
The first warning was issued on the morning of the 20th based on satellite and synoptic data. Early the next morning reconnaissance aircraft reported a central pressure of 989 mb and TD-19 was upgraded to Tropical Storm Flossie.
Midtropospheric ridging extending from the central North Pacific to the northern portion of the South China Sea was the controlling factor in steering Flossie. A weakness developed in this ridge during the next few days, pro ducing extremely weak steering flow. This caused the storm to follow an erratic track during the period from 200000Z to 211200Z.
kno A container ship, the SS Mayaquez, reported a pressure of 980 mb and 60 knot winds on the afternoon of the 21st. At that time the Mayaquez was 40 nm south-southwest of the storm center. Flossie was upgraded to typhoon on the afternoon of the 22nd when located about 250 nm south of Hong Kong.
Flossie reached a maximum intensity of 70 knots on the evening of the 22nd. By the 23rd, the midtropospheric ridging was reestablished, and Flossie tracked northwest in the expected climatological direction for this area and time of year. As the typhoon approached landfall on the 23rd, its circulation was disrupted in the northeast quadrant by the terrain and its intensity began to diminish rapidly. Flossie made landfall on the afternoon of the 23rd on the northeast portion of the Luichow Peninsula. Winds at that time were down to 50 knots.
Although Typhoon Flossie's maximum winds were only 70 knots, the seas generated in the northern South China Sea remained a threat to shipping for several days. Damage Estimates/Loss of Life
Two timber freighters, the Ming Sing and Kinabalu Satu, sunk between Flossie and the southern approaches to Hong Kong on the 21st and 22nd, respec tively. Due to the high seas and typhoon force winds, all rescue efforts failed and a total of 44 men were lost. Three survivors were picked up in a lifeboat a week later.

t Vt*ov\ es4% ,xLt&6ccv K*CCLC.1t< TYPHOON IDA (6 November - 11 November, 1975)
Meteorological History/Data Destined to spend its entire life cycle at sea, Typhoon Ida was first observed as a tropical disturbance on the 4th of November, 150 nm northwest of Ponape. The disturbance initially moved westward at 8 knots with dual circulation centers oriented along a northeast to southwest axis. The disturbance became a tropical depression at 060OZ on the 6th and then began moving toward the north through a weakness in the midtropospheric subtropical ridge. The depression continued to move north at 4-5 knots for the next 24 hours while the two circulation centers consolidated into one. Early on the morning of the 8th, the depression was upgraded to Tropical Storm Ida and it accelerated toward the northwest at 10 knots. Ida continued to intensify as the center passed near the Southern Mariana Islands, with wind gusts of 32 knots reported on Guam on the 7th. On the 9th Pagan Island in the Northern Marianas reported 40-knot winds. By the 9th, Ida had come under the influence of a deep mid-latitude trough centered 600 nm to the west and began to re-curve. The storm attained typhoon intensity by 1800Z on the 9th and began tracking toward the north-northeast at an accelerated rate. A minimum central pressure of 959 mb was observed by aircraft reconnaissance at 1437Z on the 10th. By OOOOZ on the llth, Ida was moving toward the north-northeast at 33 knots and had lost much of her tropical cyclone characteristics as evidenced by satellite data. Twelve hours later, Ida had combined with a frontal system and continued to move rapidly northeastward as an extratropical system.

*i~~~e,~~4'osxOeSW' V\CL4M M0.9 _ 9 .2_3e. TYPHOON JUNE
(16 November - 24 November, 1975)
Meteorological History/Data The last typhoon of the year was to become the most intensive on record. At 0843Z on 19 November, reconnaissance aircraft measured a record low 700 mb height of 1984 m while traversing the eye and obtained a coincident minimum sea level pressure (MSLP) of 876 mb (25.87 in) by dropsonde near the cloud wall. This observation was the lowest on record, slightly lower (I mb) than Typhoons Ida in 1958 and Nora in 1973. June's central pressure well surpasses the lowest Western Hemisphere reading (892.3 mb), and that obtained by air craft in Hurricane Camille (905 mb).
June had been under frequent surveillance by satellite and aircraft since her birth in the central Carolines on the 16th. Initially, the system moved slowly westward, becoming quasi-stationary near 6N 143E (445 nm south of Guam), the result of weak steering flow near the equator. On the 18th, June began to move northward, perhaps in response to a weak ness in the 500 mb ridge caused by a deep trough approaching from the west. Simultaneously, June began to rapidly deepen, her surface pressure plummeting 52 mb in 11 hours and 90 mb in 24 hours. By the 19th, the winds of Super Typhoon June had increased to an estimated 160 knots as the typhoon reached its lowest pressure, some 230 nm west-southwest of Guam. As June tracked north-northwest toward a weakness in the 500 mb ridge, the system reached exceptionally large proportions. Sustained surface winds of 50 knots or greater extended 200 nm outward from the center. After passing abeam of Guam, Super Typhoon June turned northwest. On the-22nd, June began recurving toward northeast with maximum winds down to 115 knots. On the 23rd, the storm began accelerating rapidly in the strong westerlies and its forward speed reached nearly 60 knots with an influx of cold air. June became extratropical above 30N, still possessing winds of typhoon intensity.
Damage Estimates On the evening of the 19th, June passed approximately 200 nm to the west of Guam. More than 3,200 island residents fled into evacuation centers. There-was severe flooding in low-lying areas, with several buildings and homes damaged or destroyed by gale force winds and storm surge. A peak gust of 70 knots was recorded at Andersen AFB. Island losses amounted to an estimated $300,000 with most of the damage to crops. Eauripik Atoll in Tap district suffered severe property and crop damage. Newspaper reports stated that "sizable portions" of the island were washed into the heavy seas, but that no deaths or injuries occurred. Flooding and crop damage were also reported on Woleai Atoll and on other low-lying islands in Yap district; however, no casualties were reported on any of the islands.
