Analysis of Typhoon Koppu trajectory
Path and Moving Characteristics
Typhoon Koppu (201524) began its life over the open waters of the Northwest Pacific and followed a generally steady westward path. It formed as a tropical depression at 08:00 on October 12, 2015, at 14°N, 150.5°E, and weakened back into a tropical depression at 08:00 on October 21 at 19.3°N, 122.2°E, spanning about 28° of longitude. During its initial phase from October 12 to 14, the system mainly moved westward, with latitude fluctuating slightly between 15.5°N and 15.7°N while longitude advanced rapidly from 150.5°E to 134.9°E, indicating guidance by a steady easterly flow.
Go to Philippines以E洋面后, 路径略有N抬迹象. 10月16日至18日期间, 纬度从15.5°N缓慢上升至16.1°N, 同时经度继续W进. 10月18日03:00LandfallPhilippines吕宋岛后, 受地形摩擦及环境场变化影响, Moving速度减缓并出现轻微转 toward , 最终在吕宋岛W侧海域 toward NNE direction折返, at 10月21日消散 at S海N部边缘. 整个过程中未出现剧烈的大角度转 toward , 路径相对平直.
Intensity evolution and historical comparison
Koppu的Intensity演变经历了典型的“快速增强—巅峰维持—Landfall减弱”过程. 初始阶段Intensity较弱, 10月13日20:00才发展为Tropical Storm. 随后Go to 快速增强期, 10月16日02:00 intensified into Typhoon (33m/s) , 仅过18h便跃升为Severe Typhoon (42m/s) . 10月17日14:00达到生命史巅峰, 中心最低气压降至935hPa, max wind 达55m/s, 评定为Super Typhoon.
After making landfall on Luzon Island, Koppu rapidly weakened. By 08:00 on October 18, it had weakened to a severe typhoon with winds of 48 m/s and a central pressure of 945 hPa. It further weakened into a typhoon by 02:00 on October 19. While lingering over the northern South China Sea, it continued to weaken under unfavorable conditions and eventually returned to tropical depression intensity.
Compared with previous typhoons of the same name, Koppu was significantly stronger in 2015. The 2009 Koppu (200915) peaked only as a typhoon with a minimum pressure of 960 hPa, while the 2003 Koppu (200316) also peaked as a typhoon with a minimum pressure of 965 hPa. Koppu not only reached super typhoon intensity in 2015, but its minimum pressure of 935 hPa was 25–30 hPa lower than those of the two previous storms, indicating greater explosive development and destructive potential.
