The experiments: exp0 - single layer, double gyre (barotropic with free-surface). exp1 - 4 layer, double gyre. exp2 - 4x4 degree global simulation with steady climatological forcing. exp3 - atmospheric configuration. exp4 - flow over a Gaussian bump in open-water or channel with open boundaries. exp5 - inhomogenously forced convection in a doubly periodic box. front_relax - relaxation of a thermal front (test for GM scheme). 2D (Y-Z).
