Typhoon Koppu, international code 200316, international name KOPPU, 2003 Northwest Pacific typhoon. Formed: 2003-09-23 18:00:00, ended: 2003-09-30 06:00:00. Peak intensity: Severe Typhoon, minimum central pressure: 954 hPa, max wind: 46m/s.
Typhoon Koppu at 2003-09-23 18:00:00 at 14.5°N, 139.6°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Severe Typhoon intensity with max winds of 46 m/s (~166 km/h) and a minimum central pressure of 954hPa, recorded at 2003-09-29 06:00:00.
2003-09-30 06:00:00 After, Typhoon Koppu gradually weakened and was numbered off on 2003-09-30 06:00:00 was numbered off; its lifecycle recorded 27 track points.
2003年第16号Typhoon “Koppu”的生命史始 at Northwest Pacific洋面, 整体路径呈现典型的“NW—NE”转 toward 特征. formed初期 (9月23日至25日) , 系统中心在135°E至139°E之间徘徊, The latitude维持在14.5°N至17.2°N区间, Moving速度缓慢且 direction不定, 表现为Nameless阶段的停滞与微调. 自9月26日起, 引导气流发生变化, Typhoon 开始稳定 toward NW, During从136.7°E快速E移至140°E附近, 纬度同步N抬.
As the system N rises to lat 27° by N, the path gradually shifts from NW to NE direction. On September 29 at 06 p.m. to reach the most N end close to 30°N, the accelerated toward NE direction moves into the high latitude waters. Thro its life cycle, the Typhoon has not landfall any land, always in open ocean activity, and finally at September 30 at 06 p.m. at 35°N, 150.1°E near weakened into Tropical Storm and ended observations.
“Koppu”的Intensity演变经历了漫长的酝酿期与快速的爆发期. 在9月23日至26日的四天Time内, 系统维持NamelessIntensity, Pressure仅从1002hPa缓慢降至997hPa, wind speed在12-17m/s之间波动. 真正的增强始 at 9月27日06时, 系统在24h内由Nameless跃升为Severe Tropical Storm (30m/s, 980hPa) . 随后Go to 快速增强通道, 9月28日18时发展为Typhoon (41m/s, 963hPa) , 并 at 9月29日06时达到巅峰状态, 录得最低气压954hPa, max wind 46m/s, 定级为Severe Typhoon.
After the peak, influenced by the high latitude environment and wind shifts, intensity rapidly decreases. from the peak to dispersal only 36h, air pressure rises to 991hPa, wind speed drops to 23m/s. Compared with the same name Typhoon, 2003 'Koppu' peak intensity (954hPa) weak at 2015 'Koppu' (930hPa, Super Typhoon) , but slightly strong at 2009 'Koppu' (965hPa, Typhoon ) .
