Short summary

We have discussed the effects of discretization on dispersion of midlatitude Rossby waves on the A, B, C, CD, (DC), D, E and Z horizontal grids, and the L and CP vertical grids. The Z, C, D and CD (DC) grids generate similar dispersion of the baroclinic and barotropic Rossby modes. The A, E and B grids generate multiple (non-unique) solutions. The modes with the smallest resolvable vertical scale on the L grid do not retrograde. The CP-grid solutions are much more accurate than the L grid.
