*Climatology from historical 1981-2010 Tropical cyclone best track datasets
**Preliminary values from real-time ATCF advisories and will become final when best-tracks are available from JTWC and NHC after post-season analysis Small differences have been found in previous years between real-time and best-track ACE.
