Data sources: NOAA National Environmental Information Center IBTrACS v04r01 (Knapp et al., 2010); code 2020019S11063 / SH092020. There is no official Chinese name for this system, so the original English name is used. Intensity grades follow the classification of the local agency in the basin, converted from 1-minute sustained wind using the WMO factor, and are for reference only.
