Typhoon Sonca, international code 201116, international name SONCA, 2011 Northwest Pacific typhoon. Formed: 2011-09-15 14:00:00, ended: 2011-09-20 14:00:00. Peak intensity: Typhoon , minimum central pressure: 975 hPa, max wind: 33m/s.
Typhoon Sonca at 2011-09-15 14:00:00 at 22.1°N, 155.2°E over the Northwest Pacific; initial intensity: Tropical Storm.
It peaked at Typhoon intensity with max winds of 33 m/s (~119 km/h) and a minimum central pressure of 975hPa, recorded at 2011-09-18 02:00:00.
2011-09-20 14:00:00 After, Typhoon Sonca gradually weakened and was numbered off on 2011-09-20 14:00:00 was numbered off; its lifecycle recorded 21 track points.
2011年第16号Typhoon “Sonca”的生命周期始 at Northwest Pacific洋面, 整体路径呈现显著的NW toward 转NE toward 的抛物线型轨迹. formed初期 (9月15日至16日) , 系统位 at lat 22°至23°N, 155°至151°附近, Moving direction主要为WN, 移速相对缓慢. 随后, 受大气环流引导, Typhoon 逐渐转 toward NW, 并 at 9月17日至18日期间穿越lat 24°至30°海域. 值得注意的是, 该Typhoon 在9月18日20时左右 at lat 31.8°N, 142.5°附近达到路径最W端, 此后路径发生明显转折, 开始加速 toward NE. 整个过程中, “Sonca”始终在远洋活动, 未Landfall任何陆地, 最终 at 9月20日在lng 159°以E的高The latitude海域减弱消散. 其路径转折点清晰, 体现了典型的中纬度W风带引导下的转 toward 特征.
In terms of Intensity changes, “Sonca” underwent a complete reinforcement process to maintain the peak and then weaken. The initial stage was Tropical Storm level (18m/s, 1002hPa) , and enhanced to Severe Tropical Storm on September 17th at 08:00. On September 18th at 02:00, Pressure dropped to a minimum of 975hPa, max wind reached 33m/s, officially upgraded to Typhoon level. Then, from September 18th at 02:00 to September 20th at 02:00, Typhoonined the minimum air pressure of 975hPa and 33m/sMax of Wind for 48 hours, showing extremely strong structural stability.
Compared to History, the 2011 “Sonca” Intensity was significantly higher at the 2022 (top Tropical Storm, 998hPa) and 2017 (top Tropical Storm, 990hPa) system of the same name, but weak at 2005 No. 3 Typhoon “Sonca” (top Severe Typhoon, 950hPa) .
