Typhoon Tasha, international code 199009, international name TASHA, 1990 Northwest Pacific typhoon. Formed: 1990-07-22 06:00:00, ended: 1990-08-01 00:00:00. Peak intensity: Severe Tropical Storm, minimum central pressure: 980 hPa, max wind: 28m/s.
Typhoon Tasha at 1990-07-22 06:00:00 at 15.9°N, 126.9°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Severe Tropical Storm intensity with max winds of 28 m/s (~101 km/h) and a minimum central pressure of 980hPa, recorded at 1990-07-30 18:00:00.
1990-08-01 00:00:00 After, Typhoon Tasha gradually weakened and was numbered off on 1990-08-01 00:00:00 was numbered off; its lifecycle recorded 40 track points.
Typhoon Tasha (199009) 的生命史始 at Northwest Pacific洋面, 整体路径呈现显著的“W行后N折”特征. formed初期 (7月22日至24日) , 系统自15.9°N, 126.9°E附近 toward NW, 随后在7月24日至26日期间转 toward W direction, 横穿巴士海峡S部海域, 中心The latitude维持在20°N左右, During从124.9°E快速W移至119.5°E. 值得注意的是, 7月26日至28日期间, Typhoon 在Taiwan岛以S海域出现短暂的停滞少动现象, 经纬度变化极小, 显示其受引导气流较弱或处 at 鞍型场中. 7月29日后, 系统重新获得动力, 开始 toward NNW direction加速Moving, 最终 at 8月1日在26.7°N, 116.1°E附近减弱消散. 全生命周期内, 该Typhoon 未Landfall任何陆地, 始终在海上活动.
From the perspective of Intensity evolution, Tasha showed the characteristics of 'long-term low pressure maintenance, later short-term improvement'. In a week of Time (July 22 to July 28) , the system mainlyined at Nameless level, max wind remained between 10-15m/s, slow development. until July 29, with toward NMoving, its Intensity only began to increase significantly, from Nameless upgraded to Tropical Storm, and at July 30 at 12:00 reached peak intensity, recognized as Severe Tropical Storm, max wind recorded 28m/s (Note: The data table corresponded to 25m/s, but the peak recorded 28m/s, here with the peak value to analyze its short-term explosive power) .
与同名Typhoon 对比, 1993年的Tasha (199309) peaked at Typhoon 级, 明显强 at 1990年的Tasha (Severe Tropical Storm). 这表明虽然命名相同, 但不同年份的同名Typhoon 在能量积累和环境场支持下存在显著差异, 1990年Tasha属 at 中等偏弱的热带气旋过程.
