This research was supported by the National Science Foundation under grant ATM-0349957. This paper profited greatly from thoughtful reviews provided by Chris Landsea, an anonymous reviewer, and an Associate Editor of the Journal of Climate, as well as from informal reviews by Judith Curry and Adam Sobel. I thank Jim Kossin for generously providing his new estimates of tropical cyclone wind speed, and helping me correct for missing storms.
