Tropical Cyclone Prema
● 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).
Prema at 1983-02-25 08:00:00 (BeijingTime) 在South Pacific首次被记录, peak intensity 为Category 1 Tropical Cyclone , max wind 约 21.1 m/s (1 分钟平均) , minimum central pressure 987 hPa, at 1983-03-06 08:00:00前后结束, total 记录 37 track points (6 h一个) .

Data sources: NOAA National Environmental Information Center IBTrACS v04r01 (Knapp et al., 2010), code 1983056S11193 / SH151983. There is no official Chinese name for this system, so the original English name is used. Intensity is classified by the local agency in the relevant sea area, converted from 1-minute sustained wind using the WMO factor, for reference only. Data notes · Incorrect translation?
