AB  - Tropical cyclone (TC) rainfall is an important hazard. Radial rainfall patterns of intense overocean TCs under global warming are investigated using the MRI HighRes Coupled Model Intercomparison Project Phase 6 simulation with the SSP58.5 highemission scenario. These patterns are characterized by four parameters: rainfall at the cyclone center (To), maximum rainfall (Tm), radius of maximum rainfall (Rm), and efolding radius (Re). We find Tm strongly correlates (r = 0.8) with a moisture convergence proxy—boundarylayer maximum wind times column moisture divided by the radius of maximum wind—across differentintensities and under climate change. Under warming, mean Tm and To increase by 8.65%/K and 8.86%/K, while Rm and Re shrink by 1.03%/K and 1.79%/K, respectively. Notably, under warming, Tm exhibits greater sensitivity to TC intensity, and its increases are mainly attributed to column moisture increase.
