Abstract

A 10-level primitive-equation model designed for prediction of circulations within a limited region of the Tropics is described. The model is initialized from wind and temperature information. During the course of the integration two types of oscillations arose from the imposed horizontal boundary conditions—a short-period height oscillation and a longer period kinetic energy oscillation. The character of the two oscillations and the boundary conditions needed to remove the oscillations are described.
