Tropical Cyclone Doreen
● 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.
Doreen at 1968-01-19 08:00:00 (BeijingTime) 在South Indian Ocean首次被记录, peak intensity 为Category 1 Tropical Cyclone , max wind 约 25.7 m/s (1 分钟平均) , at 1968-01-26 14:00:00前后结束, total 记录 30 track points (6 h一个) .

Data sources: NOAA National Centers for Environmental Information IBTrACS v04r01 (Knapp et al., 2010), code 1968019S07097 / SH161968. There is no official Chinese name for this system, so the original English name is used. Intensity is classified by the local agency for the region, converted from 1-min sustained wind using the WMO factor, and is for reference only. Data notes · Incorrect translation?
