THE EFFECT OF FINITE DIFFERENCES ON THE GROWTH RATES OF UNSTABLE WAVES IN A SIMPLE BAROCLINIC MODEL

Abstract

The distortion of the growth rates of unstable baroclinic waves is investigated using implicit finite differences to replace the linearized governing equations of a two-parameter model. A variety of space and time mesh sizes are used, together with three values of static stability parameters On the whole, the introduction of finite differe ces appears to cause only a slight distortion of the growth rates over the major portion of the unstable spectrum, the long waves being less affected than the short waves. Effects due to delta are particularly minor. The finite-difference growth rates depend very slightly on the zonal wind U, in contrast to the continuous case where no such dependence is found.
