Typhoon Haitang, international code 201710, international name Haitang, 2017 Northwest Pacific typhoon. Formed: 2017-07-28 14:00:00, ended: 2017-08-01 05:00:00. Peak intensity: Tropical Storm, minimum central pressure: 984 hPa, max wind: 23m/s.
Typhoon Haitang at 2017-07-28 14:00:00 at 19.2°N, 116.2°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Tropical Storm intensity with max winds of 23 m/s (~83 km/h) and a minimum central pressure of 984hPa, recorded at 2017-07-30 14:00:00.
2017-07-30 17:30:00, Typhoon Haitang in Taiwan screen ELandfall.
2017-07-31 02:50:00, Typhoon Haitang in Fujian Fukushima Landfall.
2017-08-01 05:00:00 After, Typhoon Haitang gradually weakened and was numbered off on 2017-08-01 05:00:00 was numbered off; its lifecycle recorded 80 track points.
Typhoon Haitang (201710) 的生命史始 at S海NE部海域, 整体路径呈现显著的“NW—N—NE”折线型Moving特征. formed初期 (7月28日至29日晨) , 系统在18°N附近徘徊, During在115.4°E至116.4°E之间小幅摆动, 表现为Nameless toward Tropical Storm过渡阶段的停滞少动状态. 自7月29日18时起, 受引导气流影响, Typhoon 开始稳定 toward NW direction加速Moving, 直指Taiwan海峡S部.
7月30日17:30, Typhoon 中心 at Taiwan屏E首次Landfall, 随后穿越Taiwan岛Go to Taiwan海峡. 值得注意的是, 在穿越地形后, 系统并未显著减弱, 反而 at 7月30日18时达到peak intensity (Max Wind23m/s, minimum pressure 984hPa) . 此后路径发生明显转折, 由NW转 toward N, 并 at 7月31日02:50在Fujian福清二次Landfall. LandfallFujian后, Typhoon 继续 toward NE direction深入内陆, 最终 at 8月1日凌晨在江W境内 weakened into Nameless并 was numbered off. 整个生命周期中, track points密集, 显示其Moving速度在接近陆地及穿越海峡时有所加快.
In terms of intensity evolution, Haitang belongs to the typical 'shore-enhanced' tropical cyclone. itins the Tropical Storm level (18-20m/s) on the open ocean surface, but during the approach to Taiwan and crossing the strait, the air pressure further drops from 992hPa to 984hPa, wind speed increases to 23m/s, showing good structural integrity. however, with the second Landfall and deeper inland, influenced by ground friction and steam cuts, the intensity rapidly decreases, wind speed returns to 16-18m/s, and the air pressure rises to about 995hPa.
Compared to the 2005 Haitang Super Typhoon level (minimum atmospheric pressure 910hPa), this time the Typhoon Intensity gap is huge; that is, compared to 2011 Haitang (201118, minimum pressure 995hPa) and 2022 Haitang (202221, minimum pressure 998hPa), 2017 Haitang's minimum atmospheric pressure is lower (984hPa), peak wind speed is higher, indicating that it belongs to the same name sequence in a relatively tight structure, Intensity is slightly stronger, but has never broken Severe Tropical Storm or Typhoon level, the overall hazard range is mainly concentrated in the coastal area near Landfall.
