English Abstract:
The Laurentian Great Lakes are an important region of Canada both in terms of its natural resources and economic activity. Environment Canada has made this region a priority in its modelling efforts. In particular, Environment Canada has developed a coupled lake-atmosphere-hydrological modelling system consisting of the Canadian Regional Deterministic Prediction System (RDPS), which is based on the Global Environmental Multiscale model (GEM), the MESH (Modélisation Environnementale Surface et Hydrologie) surface and river routing model, and a hydrodynamic model based on the three-dimensional global ocean model Nucleus for European Modelling of the Ocean (NEMO) coupled to the Community Ice Code (CICE) see ice model.

Other modelling efforts in the region include: runoff comparisons with other agencies, short-term lake level forecasts, and examining effects of future climate forecasts on lake levels, streamflow, evaporation, soil moisture and snow water equivalent. This presentation will highlight the recent efforts by Environment Canada researchers to model the different aspects of the hydrological cycle within the Great Lakes.
