Tropical Cyclone Kirsty
● 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.
Kirsty at 1973-02-21 08:00:00 (BeijingTime) 在South Pacific首次被记录, peak intensity 为Category 1 Tropical Cyclone , max wind 约 22.1 m/s (1 分钟平均) , minimum central pressure 990 hPa, at 1973-03-02 20:00:00前后结束, total 记录 39 track points (6 h一个) .

There is no official Chinese name for this system, so the original English name is used. Intensity categories follow the local agency classification for the region, converted from 1-minute sustained winds using the WMO factor, and are for reference only.
