Tropical Cyclone Pearl
● 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).
Pearl at 1983-11-11 02:00:00 (BeijingTime) 在South Indian Ocean首次被记录, peak intensity 为Tropical Depression, max wind 约 18 m/s (1 分钟平均) , minimum central pressure 998 hPa, at 1983-11-15 02:00:00前后结束, total 记录 17 track points (6 h一个) .

Data sources: NOAA National Environmental Information Center IBTrACS v04r01 (Knapp et al., 2010), code 1983315S06090 / SH041984. There is no official Chinese name for this system, so the original English name is used. Intensity is classified by the local agency for the region, based on 1-minute sustained winds converted using the WMO coefficient, for reference only. Data notes · Incorrect translation?
