The present study is designed to provide both a method whereby the details of the nonlinear exchange process which occurs in the atmosphere may be considered in a simplified form, and also to indicate from some calculations the complexity of those exchanges.
It is shown that a general class of nonlinear partial differential equations -- including those frequently used in predicting atmospheric motions -- can be converted to computational form by either the "finite difference" or "spectral" method to yield formally identical equations.
