Tropical Cyclone Leslie
● 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.
Leslie at 1979-02-20 08:00:00 (BeijingTime) 在South Pacific首次被记录, peak intensity 为Category 2 Tropical Cyclone , max wind 约 30.4 m/s (1 分钟平均) , minimum central pressure 980 hPa, at 1979-02-23 20:00:00前后结束, total 记录 15 track points (6 h一个) .

Data sources: NOAA National Environmental Information Center IBTrACS v04r01 (Knapp et al., 2010), code 1979051S16187 / SH171979. There is no official Chinese name for this system, so the original English name is used. The intensity category follows the local agency classification for the region, converted from 1-minute sustained winds using the WMO factor, for reference only. Data notes · Incorrect translation?
