Data sources: NOAA National Environmental Information Center IBTrACS v04r01 (Knapp et al., 2010), code 1998287N16083. There is no official Chinese name for this system, so the original English name is used. Intensity grades follow the classification by the local agency in the relevant sea area, converted from 1-minute sustained winds using WMO factors, and are for reference only.
