Unnamed 2011 North Indian Ocean Cyclone
● 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 2011-06-16 14:00:00 (BeijingTime) 在North Indian Ocean首次被记录, peak intensity 为The Cyclone Storm, max wind 约 18.5 m/s (1 分钟平均) , minimum central pressure 978 hPa, at 2011-06-23 02:00:00前后结束, total 记录 27 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 2011167N22089. There is no official Chinese translated name for this system, so the original English name is used. Intensity grades follow the classification of the local agency for the region, converted from 1-minute sustained wind using the WMO factor, and are for reference only.
