2009North 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 2009-09-04 02:00:00 (BeijingTime) 在North Indian Ocean首次被记录, peak intensity 为The Cyclone Storm, max wind 约 20.6 m/s (1 分钟平均) , minimum central pressure 988 hPa, at 2009-09-07 14:00:00前后结束, total 记录 15 track points (6 h一个) . 曾Landfall或贴近land.

Data sources: NOAA National Environmental Information Center IBTrACS v04r01 (Knapp et al., 2010), code 2009247N19089 / IO032009. This basin has no official Chinese name, so the original English name is used. Intensity is classified by the local agency in the basin (converted from 1-min sustained wind using the WMO factor), for reference only. Data notes · Incorrect translation?
