It is widely recognized that the North American Great Lakes are particularly sensitive to climate change, and they play a critical role in regulating the regional climate. Accurate representations of lake-ice-atmosphere interactions in regional climate modeling remain one of the most crucial and unresolved issues to understand large lake systems and their watersheds. The most common representation of the Great Lakes in regional climate models (RCMs) incorporates 1-D lake models at RCM lake-grids distributed spatially across a 2-D domain.

This presentation will introduce a newly developed two-way coupled Great Lakes–Atmosphere Regional Model (GLARM) for improving the simulation of large, deep lakes in regional climate models and accurately resolving the two-way hydroclimatic interactions. Projection of the climate change over the Great Lakes region in the middle and the end of the 21st century will be also presented.
