Data sources: NOAA National Centers for Environmental Information IBTrACS v04r01 (Knapp et al., 2010), code 1991062S09168 / SH151991. This system has no official Chinese name, so the original English name is used. Intensity follows the local agency scale in the region, converted from 1-minute sustained wind using WMO factors, and is for reference only. Data notes · Incorrect translation?
