Typhoon Choi_wan, international code 200914, international name CHOI-WAN, 2009 Northwest Pacific typhoon. Formed: 2009-09-13 02:00:00, ended: 2009-09-20 08:00:00. Peak intensity: Super Typhoon, minimum central pressure: 910 hPa, max wind: 65m/s.
Typhoon Choi_wan at 2009-09-13 02:00:00 at 15.4°N, 151°E over the Northwest Pacific; initial intensity: Tropical Storm.
It peaked at Super Typhoon intensity with max winds of 65 m/s (~234 km/h) and a minimum central pressure of 910hPa, recorded at 2009-09-16 02:00:00.
2009-09-20 08:00:00 After, Typhoon Choi_wan gradually weakened and was numbered off on 2009-09-20 08:00:00 was numbered off; its lifecycle recorded 30 track points.
2009年第14号Typhoon “Choi_wan”的生命史始 at Northwest Pacific远洋海域, 整体路径呈现典型的W行后转 toward NE的抛物线形态. formed初期 (9月13日至14日) , 系统位 at lat 15°至16°N, 147°至151°之间, 受副热带高压S侧引导气流影响, 主要维持 toward WW, The latitude变化较小. 9月15日起, 随着系统 toward W推进至lng 145°附近, 路径开始显现N抬Trend, Moving direction逐渐转为NW toward .
关键的转 toward 点出现在9月17日至18日期间. 当Center到达lat 20°以N, lng 140°以W海域时, Typhoon 受W风带槽前气流影响, Moving路径发生显著转折, 由NW toward 转为NE toward 加速Moving. 此后, 系统迅速远离低The latitude暖水区, toward 高纬度Japan以E海域逼近, 最终 at 9月20日在N海道以E海域减弱并结束观测. 整个生命周期内, 该Typhoon 未Landfall任何陆地, 始终在洋面上活动.
“Choi_wan” underwent an extremely rapid enhancement process, a typical Severe Typhoon case in 2009. Starting from the September 13th Tropical Storm (18m/s, 1000hPa), it developed into a Super Typhoon in only about 48h. Especially in the 24h of September 15th 02h to 16th 02h, Pressure dropped from 940hPa to 910hPa, max wind jumped from 50m/s to 65m/s, showing extremely strong explosive power. Its peak intensityined at 910hPa and 65m/s for about 36h (September 16th 02h to 02h) , then slowly began to weaken after Go to a higher latitude, until dissipation stillined Typhoon level Intensity (33m/s).
Compared to previously the same name Typhoon, the 2009 “Choi_wan” Intensity is significantly higher. 2021 3rd Typehoon “Choi_wan” peak only Tropical Storm (995hPa) , 2015 23rd Typehoon “Choi_wan” peak Typhoon level (975hPa) , are far weaker at 2009 version. even compared to the 2003 15th Typehoon “Choi_wan” (minimum air pressure 944hPa), 2009 “Choi_wan” is lower Pressure (910hPa vs 944hPa) , wind speed greater, indicating its core structure is tighter, energy release is more intense, is at one of the strongest “Choi_wan” Typoon in history.
