Tropical Cyclone Kelvin
● 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).
Kelvin at 1991-02-24 14:00:00 (BeijingTime) 在South Pacific首次被记录, peak intensity 为Category 2 Tropical Cyclone , max wind 约 28.3 m/s (1 分钟平均) , minimum central pressure 980 hPa, at 1991-03-06 20:00:00前后结束, total 记录 42 track points (6 h一个) .

No official Chinese name is available for this region, so the original English name is used. Intensity categories follow the classifications of the relevant regional agency, converted from 1-minute sustained winds using the WMO factor, and are for reference only.
