Typhoon Winona, international code 199011, international name WINONA, 1990 Northwest Pacific typhoon. Formed: 1990-08-04 00:00:00, ended: 1990-08-11 18:00:00. Peak intensity: Typhoon , minimum central pressure: 975 hPa, max wind: 33m/s.
Typhoon Winona at 1990-08-04 00:00:00 at 28.6°N, 125.4°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Typhoon intensity with max winds of 33 m/s (~119 km/h) and a minimum central pressure of 975hPa, recorded at 1990-08-09 12:00:00.
1990-08-11 18:00:00 After, Typhoon Winona gradually weakened and was numbered off on 1990-08-11 18:00:00 was numbered off; its lifecycle recorded 32 track points.
Typhoon Winona (199011) 的生命史始 at Northwest Pacific洋面, 整体路径呈现显著的“先SW后NE”的折线型Moving特征. formed初期 (8月4日至6日) , 系统位 at lat 28°至31°N, 125°至132°之间, 主要 toward SE, The latitude从28.6°N降至27.0°N, During持续E移. 这一阶段的路径表明其受副热带高压S侧E气流引导, 同时可能受到中层W风槽或外围环流影响, 出现罕见的 toward S分量Moving.
After the system reached the most S end (about 25.5°N, 136.0°E), the Moving direction quickly shifted from SE to positive N, then gradually shifted toward NE. From August 9th, the system accelerated toward NE direction, the latitude jumped in 48h from 29.6°N to 37.9°N, the length crossing 4 lengths. This sharp turn toward and acceleration usually marks the system out of high control, and entered the W wind belt, finally at August 11th dispersed at lat 47°N to high latitude sea area.
在Intensity变化方面, Winona经历了缓慢增强至快速爆发, 随后迅速衰减的过程. 前期 (8月4日-7日) 维持Nameless等级, wind speed在7m/s至17m/s之间波动. 8月8日升级为Tropical Storm, 并在随后24h内快速加强, at 8月9日12时达到peak intensity, 中心Max Wind录得33m/s, 定级为Typhoon . 值得注意的是, 其在巅峰状态维持Time较短, 仅约12h后, 随着The latitude升高Go to 冷海水域及强垂直风切变区, intensity 开始急剧下滑. 8月10日12时已 weakened into Tropical Storm, 直至生命史结束.
Data show that the same-name Typhoon peak intensity in 1982, 1985, 1989 and 1993 did not exceed the Severe Tropical Storm level, while in 1990 Winona successfully developed to Typhoon level (33m/s), is the strongest of the listed years.
