Hurricane Ivan
● 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).
Ivan at 1980-10-01 08:00:00 (BeijingTime) 在North Atlantic首次被记录, peak intensity 为Cat 2 Hurricane, max wind 约 46.3 m/s (1 分钟平均) , minimum central pressure 970 hPa, at 1980-10-12 08:00:00前后结束, total 记录 45 track points (6 h一个) .
