Abstract: Winter circulation and thermal structure in Lake Erie is studied with a three-dimensional coupled Great Lakes Ice-circulation Model (GLIM) during 1979-1980 and 2010-2011. The hydrodynamic model has 20 vertical levels and a uniform horizontal grid size of 2 km. The model uses time-dependent wind stress and heat flux forcing at the surface which are calculated from the hourly meteorological observations obtained from National Weather Service land stations and NOAA buoys. The model reproduces several month long ice periods in both winters with maximum ice thicknesses up to 45 cm in 1979-1980. The model is validated with hourly temperature and current measurements at several moorings that were deployed in central basin of Lake Erie during both winters and additionally with ice concentration and thickness measurements in 2010-2011.
