Fig. 1: Radial distribution of linear trends (mm h−1 y−1) of tropical cyclone (TC) rain rate based on different datasets.
From: Recent global decrease in the inner-core rain rate of tropical cyclones

a The Tropical Rainfall Measuring Mission (TRMM) Multi-Satellite Precipitation Analysis (TMPA), b Global Precipitation Measurement (GPM), and c ERA5 dataset. Shaded areas indicate the standard error of linear trends of the TC rain rate. Blue: tropical storms (TSs), orange: categories 1–2 (CAT12), and red: categories 3–5 (CAT35). The vertical dotted line in each panel indicates the estimated boundary (~450 km for a global scale) of TC rainfall. All the linear trends here consider the rainy pixels only. The area-average results (considering all pixels including rainy and non-rain) are shown in Supplementary Fig. 1.
