The simulations demonstrate that the mesoscale organization of convection, a process that cannot be physically represented by conventional global climate models, is important for the variations of tropical daily accumulated precipitation extremes. In both the simulations and observations, daily precipitation extremes increase in a more organized state, in association with larger, but less frequent, storms. Repeating the simulations for a warmer climate results in a robust increase in monthly-mean daily precipitation extremes. Higher precipitation percentiles have a greater sensitivity to convective organization, which is predicted to increase with warming. Without changes in organization, the strongest daily precipitation extremes over the tropical oceans increase at a rate close to Clausius-Clapeyron (CC) scaling. Thus, in a future warmer state with increased organization, the strongest daily precipitation extremes over oceans increase at a faster rate than CC scaling. https://research-explorer.ista.ac.at/download/15047/15051/2024_ScienceAdv_Bao.pdf application/pdfno https://creativecommons.org/licenses/by/4.0/ American Association for the Advancement of Science2024 eng 2375-2548 38394192 00130004510000710.1126/sciadv.adj6801 108 https://ista.ac.at/en/news/cloud-clustering-causes-more-extreme-rain/ Bao, Jiawei, Bjorn Stevens, Lukas Kluft, and Caroline J Muller. “Intensification of Daily Tropical Precipitation Extremes from More Organized Convection.” <i>Science Advances</i>.
