1981North Indian Ocean未命名气旋
● 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).
未命名 at 1981-12-05 14:00:00 (BeijingTime) 在North Indian Ocean首次被记录, peak intensity 为特强The Cyclone Storm, max wind 约 38.6 m/s (1 分钟平均) , at 1981-12-11 02:00:00前后结束, total 记录 23 track points (6 h一个) . 曾Landfall或贴近land.

Data sources: NOAA National Environmental Information Center IBTrACS v04r01 (Knapp et al., 2010), code 1981339N11089 / IO031981. This basin has no official Chinese translated name, so the original English name is shown. Intensity is classified by the local agency in the basin and converted from 1-min sustained wind using the WMO factor, for reference only. Data notes · Incorrect translation?
