A fundamental barrier in advancing multiscale weather and climate prediction is the limited capability of contemporary models to represent the multiscale organization of precipitating convection. To overcome this, a multiscale modeling and simulation framework, which replaces the conventional cloud parameterizations with a cloud-resolving model (CRM) in each grid column of a GCM, constitutes a new and promising approach. This can provide for global coverage, two-way interactions between the CRMs and their parent GCM and explicit simulation of cloud processes and their interactions with aerosol, radiation and surface processes.

Multiscale Modeling and Simulation Group seeks to develop and apply this framework in various disciplines including weather and climate change. The current research areas in this field are:
