Tropical Cyclone Hazel
● 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.
Hazel at 1979-03-07 08:00:00 (BeijingTime) 在South Indian Ocean首次被记录, peak intensity 为Category 4 tropical cyclone , max wind 约 51.4 m/s (1 分钟平均) , minimum central pressure 938 hPa, at 1979-03-14 20:00:00前后结束, total 记录 31 track points (6 h一个) . 曾Landfall或贴近land.
