Abstract:

An efficient accurate algorithm for a barotropic model for a computational domain that encompasses the entire surface of the earth has been developed. While this simple model does not contain enough realistic features of the atmosphere to predict the synoptic-scale weather with accuracy, it does, however, simulate the planetary waves of the atmosphere with sufficient realism to enable us to conduct numerical experiments designed to study specific problems in numerical weather prediction. In this interim report, we shall give a brief discussion of the motivations for developing such a global barotropic model, describe in some detail the numerics for the solution of the model equations, and present some sample numerical time-integration results. Several remarks concerning the numerics of this algorithm are also included. Author
