Tropical Cyclone Idylle
● 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.
Idylle at 1979-04-04 14:00:00 (BeijingTime) 在South Indian Ocean首次被记录, peak intensity 为Severe Tropical Cyclone , max wind 约 52.5 m/s (1 分钟平均) , minimum central pressure 927 hPa, at 1979-04-20 08:00:00前后结束, total 记录 64 track points (6 h一个) .

Data sources: NOAA National Centers for Environmental Information IBTrACS v04r01 (Knapp et al., 2010), code 1979094S10073 / SH251979. There is no official Chinese name for this system, so the original English name is used. Intensity is classified by the local agency for the region, converted from 1-minute sustained wind using the WMO factor, and is for reference only. Data notes · Incorrect translation?
