Typhoon Nalgae trajectory
Track and Movement Characteristics
Typhoon Nalgae (201119) 的生命史始 at Northwest Pacific洋面, 整体路径呈现典型的W行Trend, 并在接近land时发生显著的路径转折. 从 formed初期的坐标 (18°N, 139.5°E) 至吕宋岛Landfall前, Typhoon 主体维持稳定的W, 纬度变化较小, 主要经度跨度大, 显示其受副热带高压S侧引导气流影响显著. 在2011年10月1日09:00Landfall吕宋岛后, 系统Go to S海N部, 路径出现明显的N翘特征. 数据显示, 从10月2日05:00的16.55°N至10月4日09:00的18.22°N, Typhoon 中心纬度持续N抬, 同时经度 toward W推进, 形成NW toward Moving路径. 这种“先W行, 后NW”的路径形态, 最终引导其 at 10月4日12:30在Hainan万宁二次Landfall. 整个生命周期历时约9天, track points密集, 显示出其在S海N部Moving速度相对放缓, 特别是在LandfallHainan前, 纬度 at 17.8°至18.2°之间徘徊, 表明环境引导气流减弱或存在地形摩擦影响.
Intensity evolution and historical comparison
Nalgae的Intensity演变经历了完整的“增强-巅峰-减弱”过程, 且爆发力极强. 初始阶段为Tropical Depression (12m/s) , 随后快速加强, 至9月30日已达Typhoon 级别 (38m/s) . 在10月1日08:00, 即首次Landfall吕宋岛前夕, 其Intensity达到巅峰, 中心最低气压降至940hPa, max wind 高达50m/s, 评定为Severe Typhoon. 然而, 受吕宋岛地形切割影响, 穿越岛屿后Intensity迅速回落, 10月2日05:00已 weakened into Typhoon (36m/s) , Go to S海后进一步降级为Severe Tropical Storm并维持较长Time. 值得注意的是, 尽管在S海期间Intensity未再大幅反弹, 但其结构得以保留, 直至第二次LandfallHainan时仍保持Tropical Storm以上Intensity.
与历届同名Typhoon 相比, 2011年Nalgae的Intensity具有压倒性优势. 2022年Nalgae巅峰仅为Typhoon (975hPa) , 而2017年及2005年的Nalgaepeak intensity仅达Tropical Storm级别 (990hPa) . 2011年Nalgae940hPa的最低气压和50m/s的Max Wind, 远超其他年份同名Typhoon , 是近几次“Nalgae”中破坏力最强的一次.
