Fig. 2: Greater ascent area fraction reduction and increases in the frequency of heavy precipitation are seen in models with higher climate sensitivity.
From: Model spread in tropical low cloud feedback tied to overturning circulation response to warming
The relationships between (a) the change in ascent area fraction (dAa/dTs; % K−1) and climate sensitivity (ECS; K), (b) dAa/dTs and the change in desent region high cloud fraction (dHCFd/dTs; % K−1), (c) the change in the frequency of heavy precipitation (dFp>10/dTs; % K−1) and ECS, and (d) dFp>10/dTs and the change in descent region upper tropospheric relative humidity (dRH250d/dTs; % K−1) for 26 CMIP6 models. The color scale from blue to red reflects increasing ECS values. All relationships shown are tropical averages (30°S-30°N), including both land and ocean points. Changes are calculated as the differences between 2086–2100 (SSP5-8.5) and 2000–2014 (historical). Values in the upper right are Pearson correlation coefficients for the regression lines shown.
