Hurricane Simon
● 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).
Simon at 1990-10-09 08:00:00 (BeijingTime) 在East Pacific首次被记录, peak intensity 为Tropical Storm, max wind 约 30.9 m/s (1 分钟平均) , minimum central pressure 990 hPa, at 1990-10-15 02:00:00前后结束, total 记录 24 track points (6 h一个) .
