Do we expect conditions for developing strong hurricanes to expand as the climate warms? If so, how fast, and which regions will be most affected? We explore these questions using an array of different climate models, to try and understand which ocean basins will have the fastest expansion and why. We analyze the expansion of hurricane environments using a combination of observations and future climate models, and find that in the Northern Hemisphere and on the western side of ocean basins, expansion is the quickest. We use a series of idealized ocean and atmosphere climate models to show that the continental setup of ocean basins and their currents are responsible for how fast environments expand. We also compare to models of Earth’s past warmer climates to understand how TC environments may change in the future. Our work suggests that future hurricane risk will not be the same across the world, and basins like the North Atlantic and West North Pacific may expand fastest.
