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 1999-06-08 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) , at 1999-06-12 02:00:00前后结束, total 记录 15 track points (6 h一个) . 曾Landfall或贴近land.

Data sources: NOAA National Centers for Environmental Information IBTrACS v04r01 (Knapp et al., 2010), code 1999159N18091 / IO031999. 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 basin, converted from 1-minute sustained winds using the WMO factor, for reference only. Data notes · Incorrect translation?
