Typhoon Etau, international code 201518, international name ETAU, 2015 Northwest Pacific typhoon. Formed: 2015-09-07 02:00:00, ended: 2015-09-09 14:00:00. Peak intensity: Tropical Storm, minimum central pressure: 990 hPa, max wind: 23m/s.
Typhoon Etau at 2015-09-07 02:00:00 at 21.5°N, 139.1°E over the Northwest Pacific; initial intensity: Tropical Storm.
It peaked at Tropical Storm intensity with max winds of 23 m/s (~83 km/h) and a minimum central pressure of 990hPa, recorded at 2015-09-08 14:00:00.
2015-09-09 08:50:00, Typhoon Etau in the Coastal Landfall of the Knowledge Peninsula.
Typhoon Etau gradually weakened and was numbered off on 2015-09-09 14:00:00 was numbered off; its lifecycle recorded 11 track points.
Typhoon Etau (201518) 的生命史相对短暂, 从 formed到消散历时约60h. 观测数据显示, 其路径呈现出典型的“先N后NW”的MovingTrend. 在9月7日02:00至9月8日02:00期间, Typhoon 中心主要沿经 toward toward NMoving, The latitude从21.5°N迅速提升至26°N, 而During变化较小 (139.1°E至138.1°E) , 表明此时引导气流以S或SW气流为主, 推动系统稳定N上.
As the latitude continues to rise to 30°N by N, Typhoon begins toward W percentage deviation, the length gradually shifts from 138.1°E to 135.9°E. Especially during the September 9th from 08:00 to 14:00, the latitude jumps from 34.4°N to 36.6°N while the length W shifts dramatically, showing the system is significantly affected by the mid-latitude W wind band in the process of approaching the island of Japan, and finally at September 9th at 08:50 in the Coastal Landfall.
In terms of intensity, Etau is shown to be slowly enhanced after maintenance peak, landfall before slightly weakened characteristics. in the initial phase (September 7, 02:00-20:00) , Pressureined at 998hPa, max wind 18m/s, intensity stable. from September 8, 08:00, air pressure dropped to 995hPa, wind speed increased to 20m/s; by September 8, 14:00 reached peak, minimum pressure 990hPa, max wind 23m/s, and under this Intensityined 36 abouth (until September 9, 08:00) . before landfall (September 9, 14:00) , air pressure rose back to 995hPa, wind speed dropped to 20m/s, showing Landfall friction and environmental change caused its Intensity weakening.
The peak intensity (Tropical Storm, 990hPa) of Etau in 2015 is the same as that of Etau (200909, Severe Tropical Storm, 990hPa) in 2009, but slightly lower than at the 2003 Super Typhoon level (minimum atmospheric pressure 933hPa) of Etau (200310), the intensity of Etau in 2015 is significantly weaker, is a medium weak tropical cyclical process, does not show very strong explosive power or persistent high intensity maintenance.
