Tropical Cyclone Hannah
● 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.
Hannah at 1972-05-08 08:00:00 (BeijingTime) 在South Pacific首次被记录, peak intensity 为Tropical Depression, max wind 约 10.3 m/s (1 分钟平均) , minimum central pressure 970 hPa, at 1972-05-12 14:00:00前后结束, total 记录 18 track points (6 h一个) . 曾Landfall或贴近land.

Data sources: NOAA National Environmental Information Center IBTrACS v04r01 (Knapp et al., 2010), code 1972129S06156 / SH301972. There is no official Chinese name for this system, so the original English name is used. Intensity is classified by the regional agency for the basin, based on 1-min sustained wind converted using the WMO factor, for reference only. Data notes · Incorrect translation?
