Global Semi-lagrangian Atmospheric Model Based on Compact Nite-diierences and Its Implementation on a Parallel Computer N ˚ 3080 Global Semi-lagrangian Atmospheric Model Based on Compact Nite-diierences and Its Implementation on a Parallel Computer
The semi-Lagrangian atmospheric model on the sphere based on compact nite diierences is presented. In the two-dimensional case, the potential vorticity is used as one of the prognostic variables. Fourth-order compact nite diierences are used to discretize rst-and second-order derivatives. The results including real data tests presented for 2D shallow water version with orography demonstrate its...

متن کاملGlobal semi-Lagrangian atmospheric model based on compact nite-di erences
The semi-Lagrangian atmospheric model on the sphere is presented. In the 2D case, the potential vorticity is used as one of the prognostic variables. The wind eld is expressed in terms of a stream function and velocity potential. Fourth-order compact nite diierences are used to discretize rst-and second-order derivatives. The results including real data tests presented for 2D shallow water vers...
متن کاملSolving a system of 2D Burgers' equations using Semi-Lagrangian finite difference schemes
In this paper, we aim to generalize semi-Lagrangian finite difference schemes for a system of two-dimensional (2D) Burgers' equations. Our scheme is not limited by the Courant-Friedrichs-Lewy (CFL) condition and therefore we can apply larger step size for the time variable. Proposed schemes can be implemented in parallel very well and in fact, it is a local one-dimensional (LOD) scheme which o...
متن کاملImplementation of the reduced grid in the shallow-water prototype of the global finite-difference SL-AV model
Today, many global spectral models apply the reduced grid (i.e. the grid where the number of points in longitude is gradually reduced while approaching the poles). The construction of the global finite-difference semi-Lagrangian SL-AV model [1] enables the implementation of the reduced grid: some part of calculations is carried out in space of Fourier coefficients in longitude. Also, the semi-L...
