Comparative Analysis of Net Basin Supply Components and Climate Change Impacts on the Upper Great Lakes Using CHARM
- Discussion on GLERL's use of regional climate models to quantify effects of climate scenarios including increased greenhouses gases on Great Lakes basin including net basin supply. GLERL's Coupled Hydrosphere-Atmosphere Research Model (CHARM) was updated from an earlier and used to simulate hydrometeorological variables in two time slices: the historical years of 1964-2000 and future projections for 2043-2070 (referred to by the centered years of 1982 and 2055, respectively). Simulated air temperature, precipitation, surface water temperature, lake evaporation and net basin supply for Great Lakes for the two time slices were compared and discussed.
