摘要內容：
As far as the representation of deep moist convection is concerned, only two kinds of model physics are used at present: highly parameterized as in the conventional general circulation models (GCMs) and explicitly simulated as in the cloud-resolving models (CRMs). Ideally, these two kinds of model physics should be unified so that a continuous transition of model physics from one kind to the other takes place as the resolution changes. In this talk, we will introduce the newly developed unified parameterization so that the physical parameterizations of a GCM converge to a global CRM as the horizontal resolution is refined. The key for this unified parameterization to succeed is to eliminate the assumption that convective clouds occupy only a small fraction of the grid size which is commonly used in the convectional parameterization of the GCM.
