Data sources: NOAA National Environmental Information Center IBTrACS v04r01 (Knapp et al., 2010), code 1999279N14315 / AL121999. 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 relevant sea area, converted from 1-min sustained wind using the WMO factor, and is for reference only. Data notes · Incorrect translation?
