Typhoon Koppu, international code 201524, international name Koppu, 2015年Northwest PacificTyphoon . formedTime: 2015-10-13 20:00:00, 结束Time: 2015-10-21 05:00:00. peak intensity: Super Typhoon, 最低Pressure: 930 hPa, max wind : 55m/s.
Typhoon Koppu at 2015-10-13 20:00:00 at 15.7°, lng 139.2° over the Northwest Pacific; initial intensity: Tropical Storm.
It peaked at Super Typhoon intensity with max winds of 55 m/s (~198 km/h) and a minimum central pressure of 930hPa, recorded at 2015-10-17 20:00:00.
2015-10-18 03:00:00, Typhoon Koppu in the Philippines Liu Song Island Landfall.
2015-10-21 05:00:00 After, Typhoon Koppu gradually weakened and was numbered off on 2015-10-21 05:00:00 was numbered off; its lifecycle recorded 53 track points.
Typhoon Koppu (201524) 的生命史始 at 2015年10月13日20时, 终 at 10月21日05时, 全程total 记录53 track points. 从经The latitude坐标序列分析, 该Typhoon 整体呈现稳定的W行路径, 随后在Landfall后出现明显的N折转 toward . formed初期 (10月13日至15日) , Center从139.2°E快速W移至130.2°E, 纬度基本维持在15.5°N至15.7°N之间, 表现为典型的纬 toward Moving特征. 随着系统接近Philippines吕宋岛, 其W行速度略有调整, 但 direction保持一致, 直至10月18日03时左右在吕宋岛Landfall.
After the landfall, the path pattern changed significantly. on October 19, 02.00 to October 21, 05.00, the length decreased slightly from 120.1°E to 121.6°E, while the latitude continued from 17.2°N to 19.4°N. This suggested that after the Typhoon crossed the land and Go to S Sea N or nearby waters, influenced by the environmental flow field, the Moving direction shifted from W to N to N direction, eventually decreasing near 19.4°N. The entire path did not show significant rotation or abnormal oscillation, and the trajectory was relatively clear.
The initial phase was Tropical Storm (18m/s, 998hPa) , within about 36h on October 16 at 02:00 to 17:00, Pressure dropped from 980hPa to 935hPa°E, max wind increased from 30m/s to 52m/s, completed the crossing from Severe Tropical Storm to Super Typhoon. on October 18 at 02:00, the system reached its peak on the eve of Landfall, minimum pressure dropped to 930hPa°E, max wind to 55m/s, establishing its Super Typhoon grade.
After Landfall Liu Song Island, affected by the ground friction and energy supply cut, the intensity sharply decreased. on October 18, at 14 o'clock, i.e. about 11h after the Landfall, the wind speed has fallen to 42m/s, the air pressure has returned to 955hPa; on October 20, at 05 o'clock, further weakened into Tropical Storm. compared to the same name History, 2015 Koppu's Intensity was significantly higher at previous record. 2009 Koppu's peak was only Typhoon level (minimum air pressure 965hPa) , 2003 Koppu for Severe Typhoon (minimum air pressure 954hPa) . 2015 Koppu not only reached a stronger Typhoon level, and its minimum air pressure (930hPa) was far lower at the
