Abstract
Finite-difference analysis of Rossby modes has been performed for two staggered hexagonal grids. The solutions are compared with those obtai ned in analytical case and for rectangular grids. The result for one o f the selected hexagonal grids better fits to the analytical solution then the results for the other considered grids. The obtained results may contribute to better understanding of the appropriateness of hexag onal grids in atmospheric and oceanographic modeling and numerical com putations.
