Tropical Cyclone Zelia
● 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).
Zelia at 2011-01-13 02:00:00 (BeijingTime) 在South Pacific首次被记录, peak intensity 为Category 4 tropical cyclone , max wind 约 48.9 m/s (1 分钟平均) , minimum central pressure 944 hPa, at 2011-01-18 14:00:00前后结束, total 记录 23 track points (6 h一个) .

Data sources: NOAA National Centers for Environmental Information IBTrACS v04r01 (Knapp et al., 2010), code 2011013S15151 / SH072011. The basin has no official Chinese name, so the original English name is used. Intensity categories follow the local agency classification for the basin, converted from 1-minute sustained winds using the WMO scale, and are for reference only. Data notes · Incorrect translation?
