It peaked at Tropical Storm intensity with max winds of 18 m/s (~65 km/h) and a minimum central pressure of 995hPa, recorded at 2011-09-25 08:00:00.
2011-09-27 08:30:00, Typhoon Haitang in Vietnam Province Landfall.
2011-09-27 11:00:00 After, Typhoon Haitang gradually weakened and was numbered off on 2011-09-27 11:00:00 was numbered off; its lifecycle recorded 47 track points.
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, The latitude显著增加而During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 WS. 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 Nameless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.
The system at September 25th 11:00 intensified into Tropical Storm, peak intensityined at 18m/s (about 8 winds), the center minimum air pressure is 995hPa. From September 25th 21:00 to September 27th 09:00 for 36h of time, its Max Wind and Pressureined highly stable, not seen significantly enhanced or weakened, indicating its location at a relatively balanced thermal power environment.
In 2005 the 5th Typhoon “Haitang” had reached Super Typhoon level, the minimum pressure is low to 910hPa, destructive; in 2017 the 10th Typhoon “Haitang” peak air pressure is 984hPa, also strong at this year’s system. even compared with the 21st Typhoon “Haitang” in 2022, the latter peak air pressure is 998hPa, although both are only Tropical Storm level, but in 2011 “Haitang” at peak intensity is lower (995hPa vs 998hPa) , showing slightly strong core structural stability.
