Abstract : Experiments are carried out with various time and space differencing schemes applied to the barotropic primitive equations using both real data and a particular stream function which is an analytic solution to the nondivergent barotropic vorticity equation. With both types of data there were some significant differences in the forecasts produced by the various schemes. Replacement of the widely used leap frog (centered) scheme by others which eliminate or lessen some of its inherent errors at the expense of more computer time or storage appears to be justified at such time when computer capacity no longer restricts operational use of these more time consuming schemes.
