The new generation of the Canadian Regional Climate Model is being developed within the framework of the existing Global
Environmental Multiscale (GEM) model presently used for global and regional numerical weather prediction at the Meteorological Service of Canada. GEM supports a number of model configurations within a single system, e.g. a regular latitude-longitude global model, a variable-resolution global model and a limited-area model (LAM), allowing a flexible approach to model development. Within the Canadian Regional Climate Modelling and Diagnostics Network, the LAM version of GEM will be used and further developed into a flexible and computationally efficient regional climate model
