Typhoon Choi_wan, international code 200315, international name CHOI_WAN, 2003 Northwest Pacific typhoon. Formed: 2003-09-17 06:00:00, ended: 2003-09-23 00:00:00. Peak intensity: Super Typhoon, minimum central pressure: 944 hPa, max wind: 51m/s.
Typhoon Choi_wan at 2003-09-17 06:00:00 at 19.4°N, 130.4°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Super Typhoon intensity with max winds of 51 m/s (~184 km/h) and a minimum central pressure of 944hPa, recorded at 2003-09-21 06:00:00.
Typhoon Choi_wan gradually weakened and was numbered off on 2003-09-23 00:00:00 was numbered off; its lifecycle recorded 24 track points.
Typhoon Choi_wan (200315) 的生命周期始 at Northwest Pacific洋面, 整体路径呈现显著的“先NW, 后NE”的抛物线型转 toward 特征. formed初期 (9月17日至18日) , 系统位 at lat 19°至23°N, 127°至130°海域, 主要 toward NW, The latitude快速提升而During变化相对平缓. 9月19日至20日期间, 随着系统N移至lat 26°以N, Moving direction逐渐由NW转为N, 随后 toward E偏移, 标志着其开始Go to W风带引导区域.
During this period, the Typhoon center from lat 29.4°N, 133.7° rapid Moving to lat 31.1°N, 137.2°, Moving direction clearly shifted to NE toward . Since then, the system accelerated toward NE direction toward, until September 23 dispersed at lat 42.1°N, 156.5° high latitude.
Choi_wan's Intensity evolution underwent a typical 'fast enhancement - peak maintenance - rapid weakening' process. Initial phase was Nameless, Pressure 1006hPa. During September 18 to 21, the system underwent explosive enhancement, Pressure dropped 62hPa within about 60h to a minimum of 944hPa, max wind climbed to 51m/s, reaching Super Typhoon level. Peak stateined about 12h on September 21 (06am to 18am) . Then, as the system toward high latitude Moving and environmental factors influenced, intensity rapidly declined, until disintegration has weakened into Severe Tropical Storm.
Its peak intensity (944hPa, 51m/s) far surpassed the Peak intensity (944hPa, 51m/s) in 2021 Choi_wan (Tropical Storm, 995hPa) and 2015 Choi_wan (Typhoon, 975hPa) . Although its intensity was slightly lower at 2009 Choi_wan (Super Typhoon, 910hPa) , in 2003 Choi_wan completed the crossing from Nameless to Super Typhoon in a shorter time, and retained a higher intensity grade in the high latitude region, showing its deep correlation core with strong structural stability.
