Typhoon Lan’s post-analysis values differ from the live values. The live values are operational positioning data during the typhoon’s active period. After Typhoon Lan dissipates, the CMA combines more complete observational data to produce the Best Track dataset. Academic research and historical rankings generally use the post-analysis values. Data sources: CMA Tropical Cyclone Best Track dataset, compiled through IBTrACS v04r01; wind speed converted from knots to m/s and rounded.
Typhoon Lan Route Characteristics
Track and Turning Characteristics
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, 纬度从24.3°N缓慢升至25.1°N, 经度由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.
Intensity evolution and historical comparison
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The minimum air pressure.降至930hPa, 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, 随着纬度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.
与同名Typhoon 对比, 2017年第21号Typhoon Lan同样达到Super Typhoon级别, 其The minimum air pressure.为925hPa. 2023年Lan的巅峰气压 (930hPa) 略高 at 2017年同类, 表明两者在peak intensity上处 at 同一量级, 均属极具破坏力的Severe Typhoon系统, 但2023年Lan在Landfall前保持了较长Time的高Intensity状态, 对沿途海域及land构成了持续威胁.
