Data sources: NOAA National Centers for Environmental Information IBTrACS v04r01 (Knapp et al., 2010), code 2020073S14149 / SH232020. There is no official Chinese name for this system, so the English name is used. Intensity categories follow the classification of the local agency in the relevant region, converted from 1-minute sustained winds using the WMO factor. For reference only.
