Data sources: NOAA National Environmental Information Center IBTrACS v04r01 (Knapp et al., 2010), code 2011354S14155. This basin has no official Chinese name, so the original English name is used. Intensity categories follow the classifications of the local agency in the basin and are converted from 1-min sustained wind using WMO factors, for reference only. Data notes · Incorrect translation?
