1958South 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 1958-11-16 14:00:00 (BeijingTime) 在South Indian Ocean首次被记录, peak intensity 为Tropical Depression, max wind 约 10.3 m/s (1 分钟平均) , at 1958-11-23 02:00:00前后结束, total 记录 27 track points (6 h一个) .

Data sources: NOAA National Environmental Information Center IBTrACS v04r01 (Knapp et al., 2010), code 1958320S08099 / SH021959. There is no official Chinese name for this system, so the original English name is shown. Intensity is classified by the regional agency based on the location, converted from 1-minute sustained winds using the WMO factor, for reference only. Data notes · Incorrect translation?
