Divergent Initialization, Experiments Using a Global Primitive, Equation Spectral Model.

Abstract

AN INITIALIZATION OF A SPECTRAL FORMULATION OF THE PRIMITIVE EQUATIONS USING A DIAGNOSTIC DIVERGENCE IS TESTED FOR A GLOBAL MODEL. The initial conditions are generated from a developing baroclinically unstable wave. A semi-implicit time scheme is developed and tested along with the usual explicit method during the course of the experiments. Results show a relatively small effect of a divergent initialization on the ensuing integrations. The semi-implicit method shows a tendency to smooth out high frequency oscillations in local tendencies. (Author)
