Data sources: NOAA National Environmental Information Center IBTrACS v04r01 (Knapp et al., 2010), code 2024037S09184 / SH112024. There is no official Chinese name for this system, so the English name is used. Intensity is classified by the local agency in the region where the system occurred, based on 1-minute sustained winds converted using the WMO factor, for reference only.
