Abstract Extreme precipitation events are projected to intensify with global warming, threatening ecosystems and amplifying flood risks. However, observation-based estimates of extreme precipitation-temperature (EP-T) sensitivities show systematic spatio-temporal variability, predominantly negative across warmer regions. Here, we attribute this variability confounding cloud radiative effects, which cool surfaces during rainfall, introducing covariation between rainfall temperature beyond temperature’s effect on atmospheric moisture-holding capacity. We remove using a thermodynamically constrained surface-energy balance, find positive EP-T continents, consistent theoretical arguments. Median observations shift from −4.9%/°C 6.1%/°C in the tropics −0.5%/°C 2.8%/°C mid-latitudes. Regional estimated is reduced by more than 40% about 30% mid high latitudes. Our findings imply that intensification after clouds accounted for.

This study investigates global extreme precipitation events (EPEs) during warm seasons, with a particular focus on EPEs preceded by heat stress (EPE-Hs) and comparative analysis those not (EPE-NHs). Using reanalysis product Earth System Model data, the spatiotemporal characteristics temperature sensitivities of are analyzed. Results show that EPE-Hs, while less frequent, have longer duration greater magnitude compared to EPE-NHs, particularly in high latitude regions. In future, significant increase is projected contrast stable EPE-NHs. EPE-Hs demonstrate substantially higher sensitivity than especially low latitudes. The precipitation-temperature scaling relationships diverge markedly between notable regional variations. These insights pivotal for crafting region-specific early warning adaptation strategies mitigate risks associated under backdrop warming.
