Data sources: NOAA National Environmental Information Center IBTrACS v04r01 (Knapp et al., 2010), code 1977177N13251 / EP021977. This area has no official Chinese name, so the original English name is used. Intensity grades follow the classifications of the local agency in the basin where the system occurred, converted from 1-min sustained wind using the WMO factor, and are for reference only.
