Typhoon Agness, international code 197505, international name PLYLLIS, 1975 Northwest Pacific typhoon. Formed: 1975-08-11 00:00:00, ended: 1975-08-18 18:00:00. Peak intensity: Super Typhoon, minimum central pressure: 920 hPa, max wind: 61m/s.
Typhoon Agness at 1975-08-11 00:00:00 at 14.2°N, 138.2°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Super Typhoon intensity with max winds of 61 m/s (~220 km/h) and a minimum central pressure of 920hPa, recorded at 1975-08-14 18:00:00.
1975-08-18 18:00:00 After, Typhoon Agness gradually weakened and was numbered off on 1975-08-18 18:00:00 was numbered off; its lifecycle recorded 32 track points.
Typhoon Agness (197505) 的生命史始 at Northwest Pacific远洋海域, 整体路径呈现典型的“先W后N再NE”的抛物线型轨迹. formed初期 (8月11日至12日) , 系统在13°N-14°N, 137°E-138°E附近徘徊, Moving速度缓慢且 direction不定, 表现为Nameless阶段的震荡调整. 自8月13日起, 受引导气流影响, 系统开始稳定 toward NW, 并迅速增强.
The key shift toward point appeared in the morning to midday period of August 15.Typhoon center position at 25.9°N-28.4°N, 137.1°E-135.8°E region, Moving direction gradually shifted from NW to positive N, then further shifted toward NE. This shift toward process accompanied by a rapid increase in latitude, from 25.9°N on August 15 to 39.5°N on August 18, the length then shifted from 137.1°EW to 1330.4°E after E. Thro the life cycle, the Typhoon did not landfall any land, always in marine activity, and eventually dispersed at Japan at E with a weakened marine zone.
From the Tropical Storm (23m/s) at 00:00 on August 13th to the Super Typhoon (56m/s) at 12:00 on August 14th, with only 36h, wind speed increased by 33m/s. Its peak intensity appeared at 00:00 on August 15th, max wind reached 61m/s,ining the Super Typhoon level about 36h (August 14th at 12:00 to 16:00).
After crossing the 30° NGo to mid-latitude region, influenced by cold sea water and vertical wind shifts, the intensity began to decrease significantly. August 16 at 12 to Severe Typhoon, August 17 at 00 to Typhoon, and August 17 at 12 to have weakened into Severe Tropical Storm.
Compared to 2004 Agness (top only for Tropical Storm, 990hPa), 1986 and 1983 Agness (all Severe Tropical Storm level), 1975 Agness reached Super Typhoon intensity with max winds of 61m/s, far over other same-year Typhoon .
