1961South Indian Ocean未命名Tropical 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 1961-02-12 02:00:00 (BeijingTime) 在South Indian Ocean首次被记录, peak intensity 为Tropical Depression, max wind 约 15.4 m/s (1 分钟平均) , at 1961-02-17 08:00:00前后结束, total 记录 22 track points (6 h一个) .

Data sources: NOAA National Environmental Information Center IBTrACS v04r01 (Knapp et al., 2010), code 1961043S09099 / SH191961. No official Chinese name is available for this system, so the original English name is used. Intensity grades are assigned by the local agency in the relevant sea area (converted from 1-min sustained wind using the WMO factor), for reference only. Data notes · Incorrect translation?
