Tropical Cyclone Atu
● 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).
Atu at 1983-12-26 14:00:00 (BeijingTime) 在South Pacific首次被记录, peak intensity 为Tropical Depression, max wind 约 18 m/s (1 分钟平均) , minimum central pressure 987 hPa, at 1983-12-31 08:00:00前后结束, total 记录 20 track points (6 h一个) .

Data sources: NOAA National Centers for Environmental Information IBTrACS v04r01 (Knapp et al., 2010), code 1983360S13174 / SH111984. There is no official Chinese name for this area, so the original English name is used. Intensity is classified by the local agency in the basin, based on 1-minute sustained winds converted using the WMO factor, for reference only. Data notes · Incorrect translation?
