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 1975-11-07 08:00:00 (BeijingTime) 在North Indian Ocean首次被记录, peak intensity 为强The Cyclone Storm, max wind 约 25.7 m/s (1 分钟平均) , at 1975-11-12 08:00:00前后结束, total 记录 21 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 1975311N11089 / IO191975. No official Chinese name exists for this system, so the English original name is used. Intensity is graded by the local agency in the basin where it occurred (converted from 1-min sustained wind using the WMO factor), for reference only. Data notes · Incorrect translation?
