The emissivity and absorptivity of the ocean are set to 1, there are no ocean currents, the atmosphere doesn't heat up and cool down with the ocean surface, the solar radiation value doesn't change through the year, the top
layer was 5 mm not 1μm, the cooler skin
layer was not modeled, a number of
isothermal layers is
unphysical compared with the real ocean of continuously varying temperatures..
