Abstract:

Short-term forecasts for Lake Erie were generated by coupling a mesoscale atmospheric prediction system with a lake forecast system. The modeling systems used were The Pennsylvania State University/National Center for Atmospheric Research (NCAR) mesoscale atmospheric prediction system, version 4.8 and the Great Lakes Forecasting System (GLFS). Two one-way coupled model runs were conducted for Lake Erie using archived 36-hour forecast output from the Penn State/NCAR model in GLFS. High-resolution (2 km) hourly lake forecasts of currents, thermal structure and surface water elevations were generated for Lake Erie out to 36 hours. The surface water elevation and water temperature forecasts were compared against observed values at selected stations.
