Data sources: NOAA National Centers for Environmental Information IBTrACS v04r01 (Knapp et al., 2010), code 2020052S11181 / SH182020. There is no official Chinese name for this system, so the original English name is used. Intensity is classified by the local agency in the region and converted from 1-minute sustained wind using the WMO scale, for reference only. Data notes · Incorrect translation?
