Abstract: Dispersion characteristics of the shallow water quasigeostrophic modes are discussed for the rectangular grids. It is shown that the propagation of the quasigeostrophic modes is affected by the orientation of the semistaggered ...

Abstract: A simple two-dimensional linearized model of the atmosphere is used to investigate behavior of the geostrophic adjustment process on five selected horizontal hexagonal grids. This study shows that hexagonal lattices have ...
