Tropical Cyclone Betsy
● Data reliability: ReliableWeather satellites monitored it throughout, so its track and intensity are relatively accurate (Atlantic and E. Pacific since 1966, other basins since 1980).
Betsy at 1981-01-30 08:00:00 (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 1981-02-04 08:00:00前后结束, total 记录 21 track points (6 h一个) .

Data sources: NOAA National Centers for Environmental Information IBTrACS v04r01 (Knapp et al., 2010), code 1981030S17190 / SH141981. There is no official Chinese name for this system, so the original English name is used. Intensity categories follow the classifications of the local agency for the region, converted from 1-minute sustained winds using the WMO factor, and are for reference only.
