Data sources: NOAA National Environmental Information Center IBTrACS v04r01 (Knapp et al., 2010), code 1990065S07083 / SH221990. This area has no official Chinese name, so the original English name is used. Intensity levels follow the classification standards of the local agency in the basin, converted from 1-minute sustained winds using the WMO factor, and are for reference only.
