Tropical Cyclone Marion
● 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.
Marion at 1977-01-11 08:00:00 (BeijingTime) 在South Pacific首次被记录, peak intensity 为Category 3 tropical cyclone , max wind 约 36 m/s (1 分钟平均) , minimum central pressure 980 hPa, at 1977-01-21 08:00:00前后结束, total 记录 41 track points (6 h一个) . 曾Landfall或贴近land.

There is no official Chinese name for this system, so its original English name is used. Intensity categories follow the classification used by the local agency in the region, converted from 1-minute sustained winds using the WMO factor, and are for reference only.
