Abstract:
Cloud feedback remains one of the largest uncertainties for long-term projection of climate change. To discuss a strategy for reducing the uncertainty in cloud feedback, it is desirable that we understand the mechanism of model cloud response to CO2 increase and how it differs among GCMs. Source term of the cloud/moisture tendency equation is expected a useful tool to illustrate the processes contributing to the cloud variation in a GCM. The present study aims at utilizing these diagnostics for understanding the inter-model difference in cloud response to CO2 increase.
