Tropical Cyclone Alex
● 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).
Alex at 1981-10-18 08:00:00 (BeijingTime) 在South Indian Ocean首次被记录, peak intensity 为Tropical Cyclone , max wind 约 43.7 m/s (1 分钟平均) , at 1981-10-27 20:00:00前后结束, total 记录 39 track points (6 h一个) .

Data sources: NOAA National Centers for Environmental Information IBTrACS v04r01 (Knapp et al., 2010), code 1981291S05081 / SH021982. 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 region where the system occurred, converted from 1-minute sustained wind using the WMO factor, and is provided for reference only.
