Data sources: NOAA National Centers for Environmental Information IBTrACS v04r01 (Knapp et al., 2010), code 1999288N15093 / IO041999. This basin has no official Chinese name, so the original English name is used. Intensity is classified by the regional agency based on the WMO-converted 1-minute sustained wind and is for reference only. Data notes · Incorrect translation?
