A modified version of the new Arakawa differencing scheme for atmospheric global circulation was programmed for a two-level, adiabatic and frictionless model. In all cases analytic initial data were used to simplify evaluation. Experiments were designed to test various terms of the primitive equations as well as over-all performance. The 48-hour forecasts were well-behaved and showed goo phase propagation.
