Tests of a Radiative Transfer Model for Numerical Prediction of the Atmospheric General Circulation.
Abstract
An evaluation is performed of a radiation model for the Naval Postgraduate School primitive-equation numerical weather prediction system. The model employs empirical expressions for atmospheric absorptivity, scattering-reflectivity, cloud-reflectivity and earth-surface reflectivity to compute solar insolation absorbed at earth and in the key atmospheric layers. The terrestrial cooling effect at earth and in these same key atmospheric layers is formulated using recent empirically-derived emissivities for the effects of both water vapor and C02. Mean seasonal atmospheric soundings for the Northern Hemisphere are used for testing the model. Heat budgets are compiled for the earth-atmosphere system, the atmospheric column and the earth's surface.
