Studies of cloud responses using GCRMs have just started. GCRM is a future tool to deepen our understanding of perturbed clouds in the climate system. GCRMs will be supplementary to the present methods using conventional GCMs with cloud parameterization. Current GCMs have ambiguities derived from cloud parameterizations, and future GCRMs have ambiguities derived from cloud microphysics schemes. However, by addressing which processes of cloud microphysics affect certain types of cloud properties, we can achieve better results. High cloud properties behave differently in a GCM and GCRM, and this drives us to ask: How is high cloud amount sensitive to cloud processes such as cloud generation processes, precipitation efficiency, or sedimentation of cloud ice? How are model results of high clouds comparable to current satellite observations such as CloudSat and CALIPSO? How can we understand the change in dynamic fields such as narrowing the precipitation regions, increase in transport of water, and relative humidity?
