Radiational Parameterization for the FNWC Primitive Equation Model Using Data Over the Oceans for 16 April 1974.
Abstract
The radiational model used in this study computes the planetary albedo and absorption of solar insolation by the ocean's surface and by atmospheric layers for the primitive equation model of FNWC. Large-scale cloud parameterization in several layers was used in these computations. Solar insolation disposition was computed from the water-mass and the cloud amounts over each gridpoint. Long-wave cooling effects were computed using emissivity formulas after Sasamori at the earth's surface and over the same layers, and were also found to be dependent upon the cloud parameterization. Two forms of the cloud parameterization were tested using FNWC data over the oceanic gridpoints for 16 April 1974. The objective was to determine the parameterization which better verified the radiational balance as a function of latitude when compared with satellite climatology at the top of the atmosphere for the same general data-period in 1969 (after Raschke, et al, 1973). The better verification resulted with the smaller cloud parameterization values.
