Typhoon Ketsana, international code 200317, international name KETSANA, 2003年Northwest PacificTyphoon . formedTime: 2003-10-18 12:00:00, 结束Time: 2003-10-26 12:00:00. peak intensity: Super Typhoon, 最低Pressure: 916 hPa, max wind : 64m/s.
Typhoon Ketsana at 2003-10-18 12:00:00 at 14.7°, lng 130.3° over the Northwest Pacific; initial intensity: Nameless.
It peaked at Super Typhoon intensity with max winds of 64 m/s (~230 km/h) and a minimum central pressure of 916hPa, recorded at 2003-10-21 12:00:00.
2003-10-26 12:00:00 After, Typhoon Ketsana gradually weakened and was numbered off on 2003-10-26 12:00:00 was numbered off; its lifecycle recorded 33 track points.
Typhoon Ketsana (200317) 的生命史始 at Northwest Pacific洋面, 整体路径呈现典型的“先W行, 后N转, 再NE toward ”的抛物线型轨迹. formed初期 (10月18日至20日) , 系统位 at 130°E至131°E之间, The latitude从14.7°N缓慢N移至15.9°N, During变化极小, 表现为近乎停滞或极其缓慢的WNMoving. 10月21日至22日, Typhoon 中心在131.1°E附近维持稳定经度, 纬度由16.4°NN抬至18.2°N, 显示其处 at 转 toward 前的关键调整期.
真正的转 toward 点出现在10月23日之后. 随着The latitude突破18.7°N, During开始显著E移, 路径由正N转为NE direction. 10月24日至26日, Typhoon 加速 toward 高纬度海域Moving, 经度从133.5°E迅速跨越至150.3°E, 纬度更是从20.4°N跃升至36.1°N. 整个生命周期内, 该Typhoon 未Landfall任何陆地, 始终在开阔洋面上活动, 最终在Japan以E远海减弱消散.
Ketsana’s Intensity evolution underwent rapid enhancement, peak maintenance and gradual weakening in three stages. Starting from October 18’s Nameless (12m/s, 1002hPa), the system rapidly intensified into Typhoon within 48h, and at October 21 at 00 reached the Severe Typhoon level (48m/s).
peak intensity维持Time较长, 从10月21日12时至10月22日12时, 连续三个观测时次保持64m/s的Max Wind和916hPa的最低气压, 显示出极强的结构稳定性. 10月23日起, 随着The latitude升高和环境场变化, intensity 开始缓慢衰减, 但直至10月24日00时仍维持Super Typhoon等级 (51m/s) . Go to 高纬度后, 受冷海水及垂直风切变影响, wind speed逐步降至33m/s, 气压回升至976hPa, 完成从Super Typhoon到普通Typhoon 的完整减弱过程. 相较 at 其他同名Typhoon , 2003年的Ketsana凭借916hPa的极低气压和64m/s的极高wind speed, 展现了罕见的远洋爆发力与持久性.
