Data sources: NOAA National Environmental Information Center IBTrACS v04r01 (Knapp et al., 2010), code 2013130N04093 / IO012013. 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 where the system occurred, based on 1-minute sustained wind converted using the WMO factor, and is for reference only.
