Model Components

Lake Treatment:

"In the Mk3.5 model, appropriate land grid points are treated in a special manner that allows for the Great Lakes and other nearby large lakes to have a more realistic representation. These grid points are allowed to freeze and thaw. These lakes modify the rate of transfer of river water to the oceans (e.g. the St. Lawrence River). This parameterization of the lakes forms part of the “newriver” option, and details are also provided in Appendix A. The subroutines involved are as for the new river routing scheme set out above." see http://www.cawcr.gov.au/technical-reports/CTR_021.pdf

"The depths of the 6 layers in the lakes are set to 3, 5, 7, 8, 8, and 8 m. These layers are used to compute changes in lake water temperature, with freezing being allowed (subroutine “surfa_riv”) . In the case of lake points, any ice produced is required to be at the surface level(s). The water is also required to stable in the vertical (see second part of subroutine 58 The CSIRO Mk3.5 Climate Model “surfa_riv”). The model results indicate that the temperature of the lowest level (6) for the lake points remains close to freezing throughout the year. "

There is no equivalent documentation for MK3.6, but presumably the model caries on the Mk3.5 characteristics.
