Typhoon Haitang trajectory
Track and Movement Characteristics
2011年第18号Typhoon “Haitang”的生命史相对短暂, 从 formed至消散历时约57h. 其路径整体呈现先N后W的折线型Moving特征. 初始阶段 (9月25日02:00至18:00) , 系统中心由15.6°N, 112.1°E toward NE至17°N, 112.1°E附近, 纬度显著增加而经度变化较小, 显示受引导气流影响 toward N推进. 随后在9月25日21:00左右出现明显转 toward , 路径转为 toward WSW. 值得注意的是, 在9月26日06:00至09:00期间, 纬度由17.6°N回落至17°N, 标志着系统完成转 toward 并稳定 toward W穿Vietnam海W部海域. 最终 at 9月27日08:30在Vietnam广治 ProvinceLandfall, Landfall后迅速 weakened into Tropical Depression并 at 当日11:00 was numbered off. 整个过程中, track points分布密集, Moving速度较为均匀, 未出现剧烈的打转或停滞现象.
Intensity evolution and historical comparison
In terms of intensity, Haitang exhibited typical characteristics of a weak tropical cyclone. The system intensified into a tropical storm at 11:00 on September 25, maintaining a peak intensity of 18 m/s (approximately Beaufort scale 8) with a minimum central pressure of 995 hPa. From 21:00 on September 25 to 09:00 on September 27, a period of 36 hours, its maximum sustained winds and central pressure remained highly stable, showing no significant strengthening or weakening, indicating it was in a relatively balanced thermodynamic environment. Intensity began to decline slowly only shortly before landfall.
Compared with previous typhoons of the same name, Typhoon Haitang (2011) was significantly weaker. The 5th typhoon of 2005, Haitang, reached super typhoon status with a minimum central pressure as low as 910 hPa, causing severe damage. The 10th typhoon of 2017, Haitang, had a peak central pressure of 984 hPa, also stronger than this year's system. Even compared to the 21st typhoon of 2022, Haitang, which had a peak central pressure of 998 hPa, although both were only at tropical storm intensity, Haitang (2011) had a lower central pressure at peak intensity (995 hPa vs 998 hPa), indicating slightly better core structural stability. Overall, Typhoon Haitang (2011) was a common tropical storm characterized by a short lifespan, weak intensity, and a regular track.
