Tropical Cyclone Dolly
● 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.
Dolly at 1970-02-11 20:00:00 (BeijingTime) 在South Pacific首次被记录, peak intensity 为Category 3 tropical cyclone , max wind 约 38.6 m/s (1 分钟平均) , minimum central pressure 965 hPa, at 1970-02-25 08:00:00前后结束, total 记录 55 track points (6 h一个) .

Data sources: NOAA National Centers for Environmental Information IBTrACS v04r01 (Knapp et al., 2010), code 1970043S15163 / SH181970. This area has no official Chinese name, so the original English name is used. Intensities are classified by the local agency for the region, based on 1-minute sustained wind converted using the WMO factor, and are for reference only. Data notes · Incorrect translation?
