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 1999-07-27 14:00:00 (BeijingTime) 在North Indian Ocean首次被记录, peak intensity 为Depressions, max wind 约 13.4 m/s (1 分钟平均) , minimum central pressure 990 hPa, at 1999-07-29 14:00:00前后结束, total 记录 9 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 1999208N21089. There is no official Chinese name for this system, so its original English name is used. Intensity is classified according to the local agency for the region, based on 1-minute sustained wind converted using the WMO scale, for reference only. Data notes · Incorrect translation?
