Abstract
To improve the simulation of nonlinear aspects of the flow over steep topography, a potential enstrophyand
energy-conserving finite-difference scheme for the shallow-water equations was derived by Arakawa
and Lamb.
Here a parallel algorithm is developed for the solution of these equations, which is based on Arakawa and
Lamb's scheme. It is shown that the efficiency of the scheme on an eight-node INTEL iPSC/2 hypercube is
81 %. Forty mesh points in the x direction and 19 in they direction were used in each subdomain.
