Tropical Cyclone Miles
● 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.
Miles at 1977-02-10 02:00:00 (BeijingTime) 在South Pacific首次被记录, peak intensity 为Category 1 Tropical Cyclone , max wind 约 23.1 m/s (1 分钟平均) , at 1977-02-13 14:00:00前后结束, total 记录 15 track points (6 h一个) .

Data sources: NOAA National Environmental Information Center IBTrACS v04r01 (Knapp et al., 2010), code 1977041S17157 / SH161977. This area has no official Chinese translated name, so the original English name is used. Intensity categories follow the classifications of the local agency in the region where the system occurred, converted from 1-min sustained wind using WMO coefficients, and are for reference only.
