1974 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 1974-11-23 08:00:00 (BeijingTime) 在North Indian Ocean首次被记录, peak intensity 为特强The Cyclone Storm, max wind 约 38.6 m/s (1 分钟平均) , at 1974-11-28 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 exists for this system, so the original English name is used. Intensity is classified by the local agency for the relevant sea area, converted from 1-minute sustained wind using the WMO scale, for reference only. Data notes · Incorrect translation?
