Hurricane Frieda
● 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.
Frieda at 1957-09-20 20:00:00 (BeijingTime) 在North Atlantic首次被记录, peak intensity 为Cat 1 Hurricane, max wind 约 38.6 m/s (1 分钟平均) , minimum central pressure 975 hPa, at 1957-09-27 20:00:00前后结束, total 记录 29 track points (6 h一个) . 曾Landfall或贴近land.
