Tropical Cyclone Val
● 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).
Val at 1980-03-25 08:00:00 (BeijingTime) 在South Pacific首次被记录, peak intensity 为Category 2 Tropical Cyclone , max wind 约 30.9 m/s (1 分钟平均) , minimum central pressure 980 hPa, at 1980-03-29 08:00:00前后结束, total 记录 17 track points (6 h一个) .
