Tropical Cyclone Nancy
● 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.
Nancy at 1977-02-12 14:00:00 (BeijingTime) 在South Pacific首次被记录, peak intensity 为Tropical Depression, max wind 约 18 m/s (1 分钟平均) , at 1977-02-13 14:00:00前后结束, total 记录 5 track points (6 h一个) . 曾Landfall或贴近land.

Data sources: NOAA National Centers for Environmental Information IBTrACS v04r01 (Knapp et al., 2010), code 1977043S16148 / SH181977. This basin has no official Chinese name, so the English name is used. Intensity is classified by the local agency in the basin, converted from 1-minute sustained wind using the WMO factor, for reference only. Data notes · Incorrect translation?
