Hurricane Nina
● 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.
Nina at 1957-11-29 08:00:00 (BeijingTime) 在Central Pacific首次被记录, peak intensity 为Cat 1 Hurricane, max wind 约 38.6 m/s (1 分钟平均) , at 1957-12-06 20:00:00前后结束, total 记录 31 track points (6 h一个) .
