The Relationship between Interannual and Long-Term Cloud Feedbacks

Summary

Analyses of CMIP5 simulations suggest that the interannual cloud feedback and long-term cloud feedback are well correlated across models. Ensemble mean vertical profiles of cloud change in response to interannual and long-term surface warming are similar, and the ensemble mean cloud feedback is positive on both timescales. Low cloud cover feedback is most responsible for this correlation, and low cloud cover sensitivity to thermodynamics partially explains the correlation.
