Distinct Dependencies of Tropical Cyclone Inner‐Core and Outer‐Region Precipitation on Translation Speed and Intensity

Abstract This study analyzes how tropical cyclone (TC) precipitation in the inner core (IC) and outer region (OR) varies with translation speed and storm intensity using satellite‐derived precipitation data. Inner core precipitation initially increases with translation speed but decreases at higher speeds, while OR precipitation increases nearly linearly with translation speed. Inner core precipitation is strongly linked to TC intensity, both with and without conditioning on translation speed, whereas OR precipitation increases with intensity primarily for stronger storms. As translation speed increases, the location of maximum precipitation shifts toward the forward‐left quadrant in the Northern Hemisphere, accompanied by a pronounced increase in rainfall magnitude. These results suggest that IC precipitation is primarily governed by storm dynamics, whereas OR precipitation is more sensitive to environmental forcing.
