THE OPERATIONAL CMC-MRB GLOBAL ENVIRONMENTAL MULTISCALE (GEM) MODEL -PART II - RESULTS

An integrated forecasting and data assimilation system has been and is continuing to be developed by the Meteorological Research Branch (MRB ) in partnership with the Canadian Meteorological Centre (CMC) of Envi ronment Canada. Part II of this two-part paper presents the objective and subjective evaluations of the intercomparison process that led to the operational implementation of the new Global Environmental Multisc ale model. The results of a ''proof of concept'' experiment and those of a meso-gamma-scale simulation further demonstrate the validity and versatility of this model.
