Tropical Cyclone Nano
● 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).
Nano at 1983-01-21 20:00:00 (BeijingTime) 在South Pacific首次被记录, peak intensity 为Category 3 tropical cyclone , max wind 约 36 m/s (1 分钟平均) , minimum central pressure 970 hPa, at 1983-01-29 08:00:00前后结束, total 记录 31 track points (6 h一个) .

Data sources: NOAA National Centers for Environmental Information IBTrACS v04r01 (Knapp et al., 2010), code 1983022S10218. There is no official Chinese name for this system, so the original English name is used. Intensity categories follow the classification used by the regional agency, converted from 1-min sustained wind using the WMO factor, and are for reference only. Data notes · Incorrect translation?
