The Feasibility of a Low-Order Model of A Moist General Circulation.
Abstract
A low-order two-level quasi-geostrophic model of a moist general circulation is formulated. The model consists of a system of 27 ordinary differential equations, or, in one variant, 20 equations. Modeled processes include evaporation from the ocean, condensation and evaporation within the atmosphere, precipitation reflection of solar radiation by clouds, and absorption and emission of long-wave radiation by clouds and water vapor. A portion of the region represented by a single grid point may be subsaturated while another portion contains clouds. A wide variety of numerical experiments may be performed with the model. When the prescribed solar heating is horizontally uniform, there are sometimes two distinct states of stable equilibrium - a very cold state and a very warm state. (Author)
