Large Scale GroupThe objective of the Large Scale Group is to maintain and improve the global medium-range forecast system from which depend the regional and local components of the Canadian forecast system. This system is based on an unified approach which can handle all aspects of environmental modeling. This strategy has lead to the development and implementation of a single dynamic core, the Global Environmental Multiscale (GEM) model. The objective of the Large Scale Group materializes in research and development in three converging directions:
These actions are now progressing in the framework of a three-dimensional variational analysis system. Adjustments will be made to take into account the new problems or constraints of the quadri-dimensional analysis system now being developped.
