Tropical Cyclone Oscar
● 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).
Oscar at 1983-02-23 02:00:00 (BeijingTime) 在South Pacific首次被记录, peak intensity 为Category 4 tropical cyclone , max wind 约 51.4 m/s (1 分钟平均) , minimum central pressure 920 hPa, at 1983-03-06 20:00:00前后结束, total 记录 48 track points (6 h一个) .
