Analysis of the Mean Forcing Fields Simulated by the Two-Level Mintz- Arakawa Atmospheric Model

Abstract

The global distributions of the mean January surface wind stress, the net diabetic heating rate, and the net rate of moisture addition as simulated in a 30-day integration with the two-level Mintz-Arakawa atmospheric general circulation model are presented. The latitudinal distributions of the zonal averages of these forcing fields are shown to be in reasonable agreement with the available observations. The most prominent discrepancies are evidently due to the model's simulation of excessive convective precipitation (and the associated convective latent heating) in the tropics, especially in the northern (winter) hemisphere. The zone of simulated tropical precipitation extends some 15 degrees poleward of the observed position, and results in a corresponding distortion of the field of evaporation minus precipitation (or moisture-addition rate).
