Unnamed North Indian Ocean Cyclone of 1997
● 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 1997-09-20 02:00:00 (BeijingTime) 在North Indian Ocean首次被记录, peak intensity 为强The Cyclone Storm, max wind 约 33.4 m/s (1 分钟平均) , minimum central pressure 984 hPa, at 1997-09-28 02:00:00前后结束, total 记录 33 track points (6 h一个) . 曾Landfall或贴近land.
