Working Group Leaders : Chin-Hoh Moeng, Hugh Morrison

Cloud-system-resolving models (CSRMs) used in MMFs or global CSRMs (GCRMs) typically use a horizontal grid size in the range
of 1 to 4 km to resolve cloud systems. However, with this range of grid spacings many important physical processes (e.g., shallow clouds, turbulence, microphysics and radiation) remain subgrid-scale (SGS) and their effects need to be parameterized.

Our objective is to improve parameterizations of these SGS physical processes in MMFs and GCRMs.
