Typhoon Vamco, international code 200910, international name Vamco, 2009年Northwest PacificTyphoon . formedTime: 2009-08-18 08:00:00, 结束Time: 2009-08-25 14:00:00. peak intensity: Super Typhoon, 最低Pressure: 935 hPa, max wind : 53m/s.
Typhoon Vamco at 2009-08-18 08:00:00 at 15.5°, lng 157.6° over the Northwest Pacific; initial intensity: Tropical Storm.
It peaked at Super Typhoon intensity with max winds of 53 m/s (~191 km/h) and a minimum central pressure of 935hPa, recorded at 2009-08-21 14:00:00.
2009-08-25 14:00:00 After, Typhoon Vamco gradually weakened and was numbered off on 2009-08-25 14:00:00 was numbered off; its lifecycle recorded 30 track points.
Typhoon Vamco (200910) 的生命史始 at Northwest Pacific远洋海域, 整体路径呈现显著的“先N后NE”的抛物线型轨迹. formed初期 (8月18日至20日) , 系统位 at 157°E附近, The latitude从15.5°N缓慢N移至19°N, During变化极小, 表现为近乎正N direction的稳定Moving. 8月21日至22日为路径的关键转折期, 系统在维持高Intensity状态下迅速 toward N推进, 纬度由19.8°N跃升至25.6°N, 随后开始受W风带引导气流影响, 路径逐渐 toward NE direction偏转. 8月23日后, 转 toward 特征愈发明显, 中心坐标从27.5°N, 155°EMoving至最终的41.3°N, 158.5°E, 经度 toward E回撤幅度增大, 标志着其完全Go to 中高纬度W风槽区. 整个过程中, 该Typhoon 未Landfall任何陆地, 始终在洋面上活动直至消散.
Vamco的Intensity演变经历了快速增强, 巅峰维持及缓慢减弱三个阶段. 初始阶段为Tropical Storm, 但在8月19日08时迅速 intensified into Typhoon , 并 at 次日08时进一步爆发为Severe Typhoon, wind speed在24h内从33m/s激增至48m/s, 气压骤降35hPa. 8月21日20时, 系统达到生命史巅峰, 中心最低气压降至935hPa°E, max wind 达53m/s, 评定为Super Typhoon. 值得注意的是, 在peak intensity附近, 系统保持了较长Time的高能状态, 从8月20日至22日上午, wind speed均维持在48m/s以上. 越过25°N后, 随着The latitude升高和海温降低, intensity 开始阶梯式减弱, 但减弱速率相对平缓, 即便在8月25日到达41.3°N的高纬度地区时, 仍保持38m/s的Typhoon 级Intensity, 显示出较强的生命力.
In the history sequence of the same name Typhoon, Vamco's 2009 Intensity significantly better at other years. compared to 2020 Vamco (top Severe Typhoon, 940hPa) , 2009 Vamco's minimum air pressure is lower (935hPa) °E, max wind is higher (53m/s vs not given specific wind speed but ranked lowest), belongs to at stronger Super Typhoon level. and with 2015 Vamco (top Tropical Storm, 995hPa) and 2003 Vamco (top Nameless, 997hPa) compared to 2009 Vamco's Intensity advantage is bigger, the latter only reached the primary or intermediate stage of tropical cycling, failed to develop to mature Typhoon .
