Tropical Cyclone Kitty
● 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.
Kitty at 1971-12-02 08:00:00 (BeijingTime) 在South Indian Ocean首次被记录, peak intensity 为Tropical Depression, max wind 约 18 m/s (1 分钟平均) , minimum central pressure 1000 hPa, at 1971-12-05 20:00:00前后结束, total 记录 15 track points (6 h一个) . 曾Landfall或贴近land.

Data sources: NOAA National Centers for Environmental Information IBTrACS v04r01 (Knapp et al., 2010), code 1971336S09139 / SH041972. There is no official Chinese name for this system, so its original English name is used. Intensity is classified by the local agency for the region, based on the WMO conversion of 1-minute sustained winds, and is provided for reference only. Data notes · Incorrect translation?
