This work was funded by the National Oceanic and Atmospheric Administration (NOAA) through the U.S. Weather Research Program (USWRP) Joint Hurricane Testbed, the National Climatic Data Center, and National Science Foundation Grant ATM-0849689. Christopher Rozoff was supported by NOAA Geostationary Operational Environmental Satellite (GOES-R) Risk Reduction Grant NA10NES4400013. Discussion with Jonathan Vigh, Derrick Herndon, Dan Vimont, and Wayne Schubert are very much appreciated. Hua Chen and Da-Lin Zhang provided Hurricane Wilma (2005) skew T–logp diagrams that helped clarify interpretation of the analyses. We also would like to thank Matthew Eastin and an anonymous reviewer for providing helpful comments that improved the quality of the manuscript.
