Unnamed North Indian Ocean cyclone of 1978
● Data reliability: Generally reliable——Aircraft entered typhoons for in situ measurements, but satellites were not yet widespread: tracks are generally accurate, while intensities may be biased, with weaker cyclones potentially going unrecorded from 1950 until the advent of satellite coverage.
未命名 at 1978-11-03 08:00:00 (BeijingTime) 在North Indian Ocean首次被记录, peak intensity 为特强The Cyclone Storm, max wind 约 41.2 m/s (1 分钟平均) , at 1978-11-13 08:00:00前后结束, total 记录 41 track points (6 h一个) . 曾Landfall或贴近land.
