1975 Unnamed North Indian Ocean Cyclone
● 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 1975-10-19 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 1975-10-24 20:00:00前后结束, total 记录 23 track points (6 h一个) . 曾Landfall或贴近land.

No official Chinese name is available for this system, so the original English designation is used. Intensity is classified by the local agency for the basin, converted from 1-minute sustained winds using the WMO coefficient, for reference only. Data notes · Incorrect translation?
