It peaked at Typhoon intensity with max winds of 38 m/s (~137 km/h) and a minimum central pressure of 965hPa, recorded at 2009-09-15 00:00:00.
2009-09-16 05:00:00 After, Typhoon Koppu gradually weakened and was numbered off on 2009-09-16 05:00:00 was numbered off; its lifecycle recorded 71 track points.
Typhoon “Koppu” (200915)’s life cycle began at 13 September 2009 at 02:00, ended at 16 September 2009 at 05:00, not landfall land. From the space trajectory, the Typhoon overall presented a stable NW toward MovingTrend. In the initial phase (13 September 2009 at 02:00 to 17:00) , system position at lat 18.8° to 19.4°N, between 121° to 118.7°, Moving direction mainly for WN, the latitude changes small, the length toward W advance significant. Go to 14 September, the path appears obvious N fractures, from 14 September 04:00 to 20:20°NN gradually up to 15 April 20th at 229.9°N, while continuing toward W deep. During the entire process, Typhoon’s center coordinates continuous changes, according to
In terms of Intensity changes, “Koppu” underwent a complete “enhanced-top-weakened” process. Initiallyining the Tropical Storm level (18-20m/s) , air pressure at 1000-998hPa. From September 14, at 04 am, wind speed increased to 23m/s, air pressure dropped to 990hPa, then rapidly strengthened. On September 14, at 14 am upgraded to Severe Tropical Storm (30m/s) , and at the same day at 19 am reached the Typhoon level (33m/s) . The system reached peak intensity, max wind 38m/s, minimum pressure 965hPa. Peak stateined Time is shorter, only about 5h after, since September 15, 10 am, wind speed 24h began to rapidly weaken, from 30m/s to 13
In 2015 the 24th Typhoon “Koppu” peak intensity to Super Typhoon level, minimum pressure is lower to 930hPa; in 2003 the 16th Typhoon “Koppu” also reaches Severe Typhoon level, minimum pressure is 954hPa.
