Tropical Cyclone Costa
● 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).
Costa at 1986-01-07 14:00:00 (BeijingTime) 在South Indian Ocean首次被记录, peak intensity 为Tropical Cyclone , max wind 约 36 m/s (1 分钟平均) , minimum central pressure 976 hPa, at 1986-01-19 14:00:00前后结束, total 记录 49 track points (6 h一个) .
