Typhoon Lan, international code 202307, international name Lan, 2023年Northwest PacificTyphoon . formedTime: 2023-08-08 08:00:00, 结束Time: 2023-08-17 14:00:00. peak intensity: Super Typhoon, 最低Pressure: 930 hPa, max wind : 55m/s.
Typhoon Lan at 2023-08-08 08:00:00 at 24.3°, lng 149° over the Northwest Pacific; initial intensity: Tropical Storm.
It peaked at Super Typhoon intensity with max winds of 55 m/s (~198 km/h) and a minimum central pressure of 930hPa, recorded at 2023-08-11 08:00:00.
2023-08-15 05:00:00, Typhoon Lan Landfall in the wetland area of Japan and Hokkaido County.
2023-08-17 14:00:00 After, Typhoon Lan gradually weakened and was numbered off on 2023-08-17 14:00:00 was numbered off; its lifecycle recorded 56 track points.
Typhoon Lan (202307) 的生命周期始 at Northwest Pacific洋面, 整体路径呈现典型的“NW行—N折—NE移”的抛物线形态. formed初期 (8月8日至10日) , 系统中心稳定 toward NW, The latitude从24.3°N缓慢升至25.1°N, During由149°EW移至143.9°E. 随后, 受副热带高压边缘气流引导, 路径逐渐转为N direction. 8月11日至12日期间, Typhoon 在142°E附近经历明显的转 toward 过程, Moving direction由正N逐步调整为NE toward . LandfallJapan和歌山 County潮岬地区后 (8月15日05:00) , 系统继续 toward NE direction深入, 最终 at 8月17日14:00在44.9°N, 139.3°E附近减弱消散. 整个路径跨度大, 从低纬度热带海域一直延伸至中高纬度地区, track points分布均匀, 显示了其长寿命且Moving稳定的特点.
Lan的Intensity变化经历了快速增强, 巅峰维持及Landfall后衰减三个阶段. 初始阶段为Tropical Storm (18m/s) , 随后在3天内迅速加强. 8月11日17:00, 其在27.6°N, 142.8°E达到peak intensity, 确认为Super Typhoon, 中心最低气压降至930hPa°E, max wind 达55m/s. 巅峰过后, 受环境场影响, intensity 出现波动, 8月12日短暂 weakened into Severe Typhoon (42m/s) , 但在8月14日又略有回升至40m/s. 8月15日Landfall时, intensity 维持在Typhoon 级别 (35m/s) . Landfall后, 随着The latitude升高及下垫面摩擦增加, 系统迅速减弱, 8月16日降级为Tropical Storm, 直至生命终结.
Compared to the same name Typehoon, the 21st Typehoon Lan in 2017 also reached the Super Typhoon level, with its lowest air pressure of 925hPa. 2023 Lan's peak air pressure (930hPa) is slightly higher at the same level in 2017, indicating that both at the same level at peak intensity, are highly destructive Severe Typhoon systems, but in 2023 Lan hasined a longer Time High Intensity state before Landfall, along the sea and land constituting a continuing threat.
