2002 Unnamed Cyclone in the North Indian Ocean
● 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 2002-12-21 14:00:00 (BeijingTime) 在North Indian Ocean首次被记录, peak intensity 为Depressions, max wind 约 18 m/s (1 分钟平均) , minimum central pressure 1000 hPa, at 2002-12-26 02:00:00前后结束, total 记录 19 track points (6 h一个) .

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 (converted from 1-min sustained wind using the WMO factor) and is for reference only. Data notes · Incorrect translation?
