Tropical Cyclone Agatha
● 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.
Agatha at 1972-03-22 08:00:00 (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 1972-03-28 08:00:00前后结束, total 记录 25 track points (6 h一个) .

Data sources: NOAA National Environmental Information Center IBTrACS v04r01 (Knapp et al., 2010), code 1972082S15199 / SH261972. There is no official Chinese name for this system, so the original English name is used. Intensity categories follow the classifications of the relevant regional agency and are converted from 1-minute sustained winds using the WMO factor for reference only.
