Data sources: NOAA National Environmental Information Center IBTrACS v04r01 (Knapp et al., 2010), code 1980088S14140 / SH271980. This system has no official Chinese name, so the original English name is used. The intensity category follows the classifications of the local agency in the basin, converted from 1-minute sustained winds using the WMO factor, and is for reference only.
