a Population density map for 2020 from the Gridded Population of the World, Version 4 (GPW V4.11) (1° × 1°). b Topography from NCEI ETOPO 2022. Linear trends of RH for c ERA5 and d CESM2-LE. CESM2 and ERA5 cover the period from 1961 to 2020. Dotted areas indicate statistically significant trends (P < 0.05). The black box in (a) is defined as the IGP in this study.
