Tropical Cyclone Monica
● 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.
Monica at 1974-01-15 20:00:00 (BeijingTime) 在South Pacific首次被记录, peak intensity 为Category 1 Tropical Cyclone , max wind 约 22.1 m/s (1 分钟平均) , minimum central pressure 990 hPa, at 1974-01-20 20:00:00前后结束, total 记录 21 track points (6 h一个) .

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