Data sources: NOAA National Centers for Environmental Information IBTrACS v04r01 (Knapp et al., 2010), code 1997018S11059 / SH201997. There is no official Chinese name for this system, so the original English name is used. Intensity grades follow the classifications of the relevant regional agency and are converted from 1-minute sustained winds using the WMO factor for reference only.
