Cyclone Phyan
● Data reliability: ReliableWeather satellites monitored it throughout, so its track and intensity are relatively accurate (Atlantic and E. Pacific since 1966, other basins since 1980).
Phyan at 2009-11-09 14:00:00 (BeijingTime) 在North Indian Ocean首次被记录, peak intensity 为强The Cyclone Storm, max wind 约 25.7 m/s (1 分钟平均) , minimum central pressure 988 hPa, at 2009-11-11 20:00:00前后结束, total 记录 10 track points (6 h一个) . 曾Landfall或贴近land.
