Data sources: NOAA National Centers for Environmental Information IBTrACS v04r01 (Knapp et al., 2010), code 1984361S08178 / SH071985. No official Chinese name is available for this basin, so the original English name is used. Intensity categories follow the local agency classification in the basin, converted from 1-minute sustained wind using the WMO factor, and are for reference only. Data notes · Incorrect translation?
