Tropical Cyclone Nadine
● 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.
Nadine at 1978-03-18 14:00:00 (BeijingTime) 在South Indian Ocean首次被记录, peak intensity 为Severe Tropical Storm, max wind 约 28.8 m/s (1 分钟平均) , minimum central pressure 976 hPa, at 1978-03-23 14:00:00前后结束, total 记录 21 track points (6 h一个) .
