Typhoon Choi_wan, international code 201523, international name Choi-wan, 2015 Northwest Pacific typhoon. Formed: 2015-10-02 20:00:00, ended: 2015-10-08 08:00:00. Peak intensity: Typhoon , minimum central pressure: 975 hPa, max wind: 33m/s.
Typhoon Choi_wan at 2015-10-02 20:00:00 at 18.9°N, 166.6°E over the Northwest Pacific; initial intensity: Tropical Storm.
It peaked at Typhoon intensity with max winds of 33 m/s (~119 km/h) and a minimum central pressure of 975hPa, recorded at 2015-10-07 02:00:00.
2015-10-04 14:10:00, Typhoon Choi_wan in Guangdong Zhanjiang sloping area coastal Landfall.
2015-10-08 08:00:00 After, Typhoon Choi_wan gradually weakened and was numbered off on 2015-10-08 08:00:00 was numbered off; its lifecycle recorded 23 track points.
Typhoon Choi_wan (201523) 的生命史始 at Northwest Pacific远洋海域, 整体路径呈现显著的“NW行—N转—NE移”的三段式特征. formed初期 (10月2日至4日) , 系统位 at 166°E附近, 受副热带高压引导, 稳定 toward NW, The latitude从18.9°N缓慢上升至20.7°N, During toward W推进约8个经度. 10月4日14:10, 该系统在GuangdongZhanjiang坡头区coastal 完成Landfall, 此时Intensity仍维持Tropical Storm级别.
After the landfall, Choi_wan did not disperse rapidly, but continued toward NW deeper inland and gradually turned toward N. During the 5th to 6th of October, its central length moved from 155.2°E to 150.6°E, the latitude from 21.3°N rapidly increased to 25.4°N, Moving speed significantly accelerated, showing the Go to W wind belt acceleration trend. On the morning of 7th of October, the system reached the twist point near the N-end of the path at 26.5°N, 150.6°E, then turned to NE, and finally at 8th of October at 08:00 at 40.5°N, 148.2°E weakened.
Choi_wan的Intensity演变具有“先弱后强, Landfall后增强”的非典型特征. formed初期至Landfall前, 其Intensity维持在Tropical Storm级 (18-23m/s) , 气压在998-990hPa之间波动. 值得注意的是, 系统在10月4日LandfallGuangdong后, intensity 不降反升, at 10月4日20:00 intensified into Severe Tropical Storm, 并在随后的N上过程中持续增强. 10月7日02:00, 其在26.5°N附近达到peak intensity, max wind 33m/s, minimum pressure 975hPa, 正式升级为Typhoon 级. 此后受高The latitude冷空气及海面Temperature降低影响, intensity 逐渐减弱, 直至消散.
Compared with the historical typhoon, 2015 Choi_wan's Intensity at the middle down level. 2009 Choi_wan (200914) and 2003 Choi_wan (200315) both developed into Super Typhoon, minimum pressure lower to 910hPa and 944hPa respectively, far above 2015 Choi_wan's 975hPa. and 2021 Choi_wan (202103) peaked only for Tropical Storm, Air Pressure 995hPa, intensity weak at 2015 version.
