Typhoon Sudal, international code 200401, international name SUDAL, 2004年Northwest PacificTyphoon . formedTime: 2004-04-08 08:00:00, 结束Time: 2004-04-16 14:00:00. peak intensity: Severe Typhoon, 最低Pressure: 940 hPa, max wind : 50m/s.
Typhoon Sudal at 2004-04-08 08:00:00 at 9.1°, lng 140.6° over the Northwest Pacific; initial intensity: Typhoon .
It peaked at Severe Typhoon intensity with max winds of 50 m/s (~180 km/h) and a minimum central pressure of 940hPa, recorded at 2004-04-09 20:00:00.
2004-04-16 14:00:00 After, Typhoon Sudal gradually weakened and was numbered off on 2004-04-16 14:00:00 was numbered off; its lifecycle recorded 32 track points.
Typhoon Sudal (200401) 的生命史始 at Northwest Pacific低The latitude海域, 整体路径呈现典型的“抛物线”型Moving特征. formed初期 (4月8日至10日) , 系统位 at lat 9°至11°之间, 受副热带高压S侧E气流引导, 稳定 toward WN. 在此期间, During从140.6°E快速W移至135.2°E, 横 toward 跨度显著.
关键的转 toward 节点出现在4月12日前后. 数据显示, 4月12日08:00至20:00, Typhoon 中心During维持在131°E不变, The latitude由15.5°N微升至16.1°N, 表明此时系统Moving速度减缓并Go to 停滞少动阶段, 随后开始逐渐转 toward NE direction. 4月13日起, 路径明显转为NE toward , 经度重新 toward E回溯, 至4月16日消散时已到达150.7°E. 整个过程中, Typhoon 未Landfall任何陆地, 始终在洋面上活动, 最终在高纬度海域减弱消散.
Sudal’s Intensity change underwent three stages of “fast enhancement – peak maintenance – slow weakening”.Starting at Typhoon level (35m/s, 970hPa) on April 8, the system rapidly intensified into Severe Typhoon within 24h, and at April 9 at 20:00 reached peak intensity°E, max wind 50m/s, minimum pressure 940hPa.
值得注意的是其巅峰状态的持久性. 从4月9日20:00至4月14日08:00, 长达近5天的Time内, Sudal始终维持在Severe Typhoon级别, wind speed保持在45-50m/s区间, 气压稳定在940-950hPa. 这种长Time的高Intensity维持在W太平洋早季Typhoon 中较为罕见. 4月14日20:00后, 随着The latitude升高至22.2°N以上, 系统开始减弱, wind speed降至40m/s以下, 气压回升. 至4月16日14:00, intensity 降为Tropical Storm (20m/s, 990hPa) , 生命史终结. 相较 at 其他同名或同期Typhoon , Sudal在4月份即达到Severe Typhoon级别且维持Time长, 显示出极强的能量积累与结构稳定性.
