Experiments with a 5-Level Global Primitive Equation Atmospheric Model Using Analytically Determined Fields.

Abstract

A description of the FNWC five level baroclinic, global, primitive equation model is presented including the finite difference equations used. Analytic initial data is generated in order to avoid the complications caused by real data with respect to verification. A comparison of second order differencing versus mixed second and fourth order differencing shows that the latter gives relatively more accurate propagation for smaller scale disturbances than the former. In addition various experiments are conducted to improve the model's treatment of cross-polar flow.
