Typhoon Agness, international code 197807, international name AGNESS, 1978 Northwest Pacific typhoon. Formed: 1978-07-24 00:00:00, ended: 1978-07-30 06:00:00. Peak intensity: Severe Tropical Storm, minimum central pressure: 980 hPa, max wind: 25m/s.
Typhoon Agness at 1978-07-24 00:00:00 at 16.5°N, 114.7°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Severe Tropical Storm intensity with max winds of 25 m/s (~90 km/h) and a minimum central pressure of 980hPa, recorded at 1978-07-26 06:00:00.
1978-07-30 06:00:00 After, Typhoon Agness gradually weakened and was numbered off on 1978-07-30 06:00:00 was numbered off; its lifecycle recorded 26 track points.
Typhoon Agness (197807) 的生命史始 at S海NE部海域, 整体路径呈现显著的“W进-停滞-折返”复杂形态. formed初期 (7月24日至25日) , 系统受引导气流影响, 稳定 toward NW, The latitude从16.5°N迅速N抬至21.2°N, During由114.7°EW移至115.7°E, 显示出较强的 toward N分量. 7月26日凌晨, 系统在21.5°N附近达到最W端Position后, Moving direction发生关键转折, 转为近乎正W direction平行 at 海岸线Moving.
It is noteworthy that during the period 27-28 July, the Typhoon center wandered within a narrow area of 20.9°N to 21.3°N, 111.9°E to 113.3°E, and the Moving speed markedly slowed, showing typical stagnant minority characteristics. subsequently, since July 29, the path showed a rare toward E twist phenomenon, the system re-toward NE, eventually at July 30 06:00 at 23.4°N, 115.1°E weakened dispersal.
在Intensity变化方面, Agness经历了缓慢增强至巅峰后长期维持, 最后逐渐减弱的过程. 系统从Nameless起步, wind speed由10m/s逐步攀升, at 7月26日12:00达到peak intensity, 定性为Severe Tropical Storm, max wind 25m/s. 此后近三天Time内 (7月26日晚至7月29日中午) , 其Intensity高度稳定, max wind 持续维持在23m/s的Tropical Storm级别, 未出现剧烈波动. 直至7月30日凌晨, 随着系统N移及环境条件变化, wind speed降至20m/s并最终 weakened into Nameless.
Its peak intensity (Severe Tropical Storm, 25m/s) weak at 1989 Agness (Super Typhoon) and 1986 Agness (Severe Tropical Storm) , with 1983 Agness flat, but slightly strong at 2004 Agness (Tropical Storm) .
