1958South Pacific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 1958-03-11 14:00:00 (BeijingTime) 在South Pacific首次被记录, peak intensity 为Tropical Depression, max wind 约 18 m/s (1 分钟平均) , at 1958-03-19 20:00:00前后结束, total 记录 34 track points (6 h一个) .

Data sources: NOAA National Centers for Environmental Information IBTrACS v04r01 (Knapp et al., 2010), code 1958070S13175 / SH221958. This system has no official Chinese name, so the original English name is used. Intensity is classified by the local agency for the region, based on 1-minute sustained wind converted using WMO factors, for reference only. Data notes · Incorrect translation?
