Typhoon Vanessa, international code 199103, international name VANESSA, 1991 Northwest Pacific typhoon. Formed: 1991-04-20 12:00:00, ended: 1991-04-28 18:00:00. Peak intensity: Tropical Storm, minimum central pressure: 994 hPa, max wind: 23m/s.
Typhoon Vanessa at 1991-04-20 12:00:00 at 3.9°N, 145°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Tropical Storm intensity with max winds of 23 m/s (~83 km/h) and a minimum central pressure of 994hPa, recorded at 1991-04-26 18:00:00.
1991-04-28 18:00:00 After, Typhoon Vanessa gradually weakened and was numbered off on 1991-04-28 18:00:00 was numbered off; its lifecycle recorded 34 track points.
Typhoon Vanessa (199103) 的生命周期始 at 1991年4月20日12时, formedPosition位 at lat 3.9°N, 145°附近的热带洋面. 从整体路径来看, 该系统呈现出自SE toward NW direction稳定Moving的态势, 全程未出现明显的路径转折或回旋现象. 在 formed初期 (4月20日至21日) , 系统The latitude基本维持在3.9°N附近, 主要进行 toward W的横 toward Moving; 随后自4月22日起, 随着纬度逐渐N抬至4°N以上, 路径转为典型的NW toward 推进. 直至4月28日18时消散 at lat 20.3°N, 111.7°附近, 其Moving轨迹平滑, 覆盖了从W太平洋深处至S海N部的广阔海域. 值得注意的是, 该Typhoon 在整个生命史中无Landfall记录, 始终在海上活动, 最终在接近陆地边缘的高纬海域减弱消散.
在Intensity变化方面, Vanessa经历了从Nameless到Tropical Storm再回归Nameless的完整过程. 系统 formed初期Intensity较弱, 维持7m/s的wind speed长达约48h. 自4月22日中午起, wind speed开始缓慢提升, 经过数日的持续加强, at 4月26日12时正式升级为Tropical Storm, 并在4月27日00时达到peak intensity, max wind 录得23m/s. 巅峰状态维持Time较短, 随后受环境因素影响, intensity 迅速回落, at 4月28日凌晨降级为Nameless, 并最终减弱消亡.
Its peak intensity is only at the Tropical Storm level, compared with the 1994 (199407) and 1988 (198804) typhoon of the same name, all belonging to the medium weak tropical cyclone. however, compared to the 1984 16th typhoon Vanessa (198416) had reached the 'Super Typhoon' level, the 1991 process has a significant gap in energy accumulation and destruction potential, reflecting the intensity difference of the same name typhoon in the different climate context.
