The 1987 Unnamed 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 1987-10-30 08:00:00 (BeijingTime) 在North Indian Ocean首次被记录, peak intensity 为强The Cyclone Storm, max wind 约 28.3 m/s (1 分钟平均) , minimum central pressure 984 hPa, at 1987-11-03 20:00:00前后结束, total 记录 19 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 1987303N06088 / IO051987. This basin has no official Chinese name, so the original English name is used. Intensity grades follow the classifications of the relevant local agencies, converted from 1-min sustained wind using the WMO factor, and are provided for reference only.
