Tropical Cyclone Tomasi
● 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).
Tomasi at 1983-03-27 08:00:00 (BeijingTime) 在South Pacific首次被记录, peak intensity 为Category 4 tropical cyclone , max wind 约 52.5 m/s (1 分钟平均) , minimum central pressure 925 hPa, at 1983-04-05 08:00:00前后结束, total 记录 37 track points (6 h一个) .
