1. Representation of the Great Lakes in CRCM5 using 3D ocean model NEMO: impacts on simulated climate
Huziy O and Sushama L

2. Experiment setup Simulation period: 1979–2010
Analysis period: 1990–2010
Time step: 5 min
Horizontal resolution: 0.1°
Domain size: 440 by 210
2 model configurations:
Great Lakes (GL) using Hostetler (1D) model
GL using NEMO (3D) model
Driving data: ERA-Interim at 0.75° resolution

3. Analysis plan
Validate precipitation, Tmin and Tmax with the Hopkinson-based observation dataset, compare biases in the cases of the NEMO and Hostetler simulated Great Lakes.
Study impact of the changed lake model on the vertical structure of the atmospheric column: temperature and humidity profiles, boundary layer height.
Analyze changes to simulated snowfall and liquid precipitation
Analyze impacts on lake-effect snowfall

4. Output variables
Air temperature, humidity and winds on pressure levels
Temperature and humidity tendencies
Radiative fluxes
Streamflow, runoff
Lake ice depth, lake temperature
