scripts for "Tropical cyclones expand faster at warmer relative sea surface temperature"

Scripts for generating the figures of the paper "Tropical cyclones expand faster at warmer relative sea surface temperature" by Wang, Chavas, and Schenkel. Three folders are each for analyses of reanalysis r8, besttrack r17, and aquaplanet r8, respectively. read file data_description for scripts and data used for Figs. 1-3. Look for nc files for data in version 1 and 2 (use the file in the newer version if it is duplicate in the old version).
