A three dimensional staggered grid model, based on the Boussinesq equations, is developed and applied to mesoscale waves. The model is tested with a three-dimensional stable gravity wave and forecasts for 40 time steps are compared with the analytic solutions and also with a full grid model. Comparisons show very good agreement with both forecasts for the stated time. Failure of the relaxation scheme to meet the convergence criterion after 47 time steps is discussed. Author
