The authors thank NOAA/HRD for providing access to the processed radar data. We are especially grateful to Rob Rogers for showing us this dataset and also pointing us to previous work on the subject. We would also like to thank Steve Durden at the NASA Jet Propulsion Laboratory for providing information about the APR-2 radar data. Nick Shay and colleagues at the University of Miami’s Rosenthiel School of Marine and Atmospheric Science (RSMAS) provided the OHC data. The authors are grateful for the reviews of Mike Fiorino, Daniel Stern, and one anonymous reviewer, whose suggestions led to significant improvement on an earlier version of this manuscript. Partial support for this project was provided by the AMS Industry Graduate Fellowship sponsored by ITT Corporation, the Florida State University Legacy Fellowship, and the NASA Genesis and Rapid Intensification Processes (Grant NNX09AC43G).
