Simulations

All simulations were done with CRCM5, the ESCER Centre's climate version of ECCC's forecast model GEM3.
All simulations were done without spectral nudging unless stated otherwise.

Ensemble: r1i1p1

* Uses empirical corrected SST and original SIC from Can-ESM, MPI-ESM-MR, MPI-ESM-LR resp. and UQAM-GEM lateral BCs from global land-atmosphere simulations, driven at the lower boundary with said SST & SIC.

Key physics parameterizations

The parameterizations used for the above CORDEX simulations are almost the same as used by Environment and Climate Change Canada for their deterministic global operational weather forecast system, described in:

Bélair, S., M. Roch, A.-M. Leduc, P. A. Vaillancourt, S. Laroche, and J. Mailhot, 2009: Medium-range quantitative precipitation forecasts from Canada’s new 33-km deterministic global operational system. Wea. Forecasting, 24, 690–708.
https://journals.ametsoc.org/view/journals/wefo/24/3/2008waf2222175_1.xml.

The main differences are:

Surface scheme CLASS instead of ISBA:
- D. L. Verseghy, 1991: CLASS--A Canadian Land Surface Scheme for GCMS: I. Soil Model. International Journal of Climatology IJCLEU, vol. p 111-133, p. 44
- D. L. Verseghy, N. A. McFarlane, and M. Lazare, 1993: CLASS-A Canadian land surface scheme for GCMS, II. Vegetation model and coupled runs. Int. J. Climatol., vol. 13, no. 4, pp. 347-370
- D. L. Verseghy, 2000: The Canadian Land Surface Scheme (CLASS): its history and future. Atmosphere-Ocean, vol. 38, no. 1, pp. 1-1
Usage of the lake scheme FLake:
