4.9. ON THE NUMERICAL RESOLUTION OF THE BOTTOM LAYER IN SIMULATIONS OF OCEA 8 : tel-00545911, version 1 - 13 Dec 2010 Fig. 1. Initial condition: temperature (left) and geostrophically adjusted velocity u(cross stream component; y-direction is upslope). Fig. 2. Temperature structure (in C o ) in the reference simulations after 2days; left: z-coordinate (G01) and right: σ coordinate (G02). Coordinates give grid in the x-direction and the z-direction for the z-coordinate grid. For the σ-coordinate results are interpolated to the z-coordinate grid (in the z-direction)
