Data sources: NOAA National Centers for Environmental Information, IBTrACS v04r01 (Knapp et al., 2010); code 1971252N29287 / AL151971. No official Chinese name is available for this system, so the original English designation is used. Intensity is classified by the local agency for the relevant ocean basin, based on 1-minute sustained wind converted using the WMO factor, for reference only. Data notes · Incorrect translation?
