Global cloud-resolving models

This review explains what distinguishes GCRMs from other types of models, the problems they solve, and the questions their more commonplace use is raising. GCRMs require high-resolution discretization over the sphere but can differ in many other respects.

They are beginning to be used as a main stream research tool. The first GCRM intercomparison studies are being coordinated, raising new questions as to how best to exploit their advantages. GCRMs are designed to resolve the multiscale nature of moist convection in the global dynamics context, without using cumulus parameterization.
