The three-dimensional balance equation are analyzed, and a multigrid algorithm with good convergence properties is developed and implemented in parallel on the shared-memory CRAY C-90 computer. An example is shown of a solution for decaying geostrophic turbulence with large Reynolds number. It exhibits a strong asymmetry in its coherent vortex dynamics: anti-cyclones on average become stronger and larger and proceed more rapidly in their merger and alignment interactions.
