Abstract
Extensive testing of the advective scheme, proposed by Prather (1986), has been carried out in support of the California Institute of Technology–Jet Propulsion Laboratory two-dimensional model of the middle atmosphere. We generalize the original scheme to include higher-order moments. In addition, we show how well the scheme works in the presence of chemistry as well as eddy diffusion. Six types of numerical experiments including simple clock motion and pure advection in two dimensions have been investigated in detail. By comparison with analytic solutions it is shown that the new algorithm can faithfully preserve concentration profiles, has essentially no numerical diffusion, and is superior to a typical fourth-order finite difference scheme.

We are indebted to M. Allen, D. Crisp, and R. Zurek for critical comments on the manuscript. We thank M. Prather for sending us the detailed derivations of his numerical scheme, and D. Stevenson for directing us to find an analytic solution for experiment 4. Special thanks axe due to one of the referees (R. Rood) for suggesting experiment 5 and for insightful comments. This work is supported by NASA grant NAGW-413 to the California Institute of Technology. Y.L.H. acknowledges the support of a Caltech SURF Fellowship in the summer of 1987. After our work had been completed, we learned that Douglass et al. (1989) successfully used Prather's method in their two-dimensional model.
