Fig. 7: Changes in static stability with warming, as well as a model’s mean-state static stability, are closely associated with subsidence rate changes.
From: Model spread in tropical low cloud feedback tied to overturning circulation response to warming
The relationship between (a) changes in descent region static stability (dSd/dTs; K K−1) and changes in the subsidence rate (dω500d/dTs; hPa day−1 K−1), (b) descent region mean-state static stability (Sd; K) and dω500d/dTs, (c) changes in tropics mean outgoing longwave radiation (dOLR/dTs; W m−2 K−1) and dSd/dTs, and (d) the mean-state frequency of heavy precipitation (Fp>10; %) and Sd 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). Values in the upper right are Pearson correlation coefficients for the regression lines shown. All relationships shown are statistically significant at the 95% confidence level.
