Fig. 4: A greater decrease in low cloud fraction corresponds to a lesser reduction of subsidence with warming.
From: Model spread in tropical low cloud feedback tied to overturning circulation response to warming
The relationship between the change in subsidence rate (dω500d/dTs; hPa day−1 K−1) and the change in descent region low cloud fraction (dLCFd/dTs; % K−1) for 26 CMIP6 models. The color scale from blue to red reflects increasing equilibrium climate sensitivity (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). The value in the upper right is the Pearson correlation coefficient for the regression line shown. The relationship is statistically significant at the 95% confidence level (p = 0.0025).
