Tropical Cyclone Errol
● 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).
Errol at 1991-03-23 20:00:00 (BeijingTime) 在South Indian Ocean首次被记录, peak intensity 为Category 4 tropical cyclone , max wind 约 56.6 m/s (1 分钟平均) , minimum central pressure 950 hPa, at 1991-04-01 02:00:00前后结束, total 记录 34 track points (6 h一个) .
