Response of Tropical Overshooting Deep Convection to Global Warming Based on Global Cloud‐Resolving Model Simulations

Abstract Tropical overshooting deep convections (ODCs) play a vital role in vertical transport of boundary layer pollutants, especially short‐lived species, to upper troposphere and lower stratosphere, with important implications for stratospheric ozone climate. We use simulations from global cloud‐system resolving model, Nonhydrostatic Icosahedral Atmosphere Model (NICAM), study ODC changes historical period the end 21st century. NICAM well reproduces Rainfall Measuring Mission‐satellite observed spatiotemporal patterns. The future occurrences ODCs cloud top height above 15.5, 16.9, 18.4 km scaled by temperature increase will 7%/K, 27%/K, 90%/K, respectively, over ocean where atmosphere is becoming warmer wetter. corresponding are −1%/K, 10%/K, 37%/K land become hotter but drier. Relative tropical cold point tropopause height, only change 3%/K, 6%/K −3%/K on land.
