1999North 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 1999-10-25 08:00:00 (BeijingTime) 在North Indian Ocean首次被记录, peak intensity 为Super Cyclonic Storm, max wind 约 72 m/s (1 分钟平均) , minimum central pressure 912 hPa, at 1999-11-03 14:00:00前后结束, total 记录 38 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 1999298N12099 / IO051999. There is no official Chinese name for this system, so the original English name is used. Intensity is classified according to the local agency in the relevant sea area, converted from 1-min sustained wind using the WMO factor, for reference only. Data notes · Incorrect translation?
