Abstract: A conservative and monotonic remapping algorithm is developed, which could be used as a component of a semi-Lagrangian transport scheme for numerical models of the atmosphere. The algorithm is a version of the monotonic ...

Abstract: Horizontal advection schemes on the semi-staggered grid E are presented, which in their linearized versions have a fourth-order space accuracy. The first is a scheme for evaluation of the horizontal nonlinear terms in the ...

Abstract: A conservative semi-Lagrangian algorithm with a snall computational diffusion is presented that may be applied to advection of passive scalars in numerical models of the atmosphere. The technique is preferable for the ...

Abstract: A simple noninterpolating semi-Lagrangian advection algorithm is presented, which uses a two-time-level scheme with minimized dissipation and dispersion errors in the Eulerian step. Advection experiments with uniform Bow ...

Abstract: Successful treatment of nonlinear momentum advection is one of the outstanding challenges for the application of rectangular quasi-uniform spherical grids in global circulation models. Quasi-uniform grids (e.g., cubic and ...

Abstract: he rapid expansion of contemporary computers is expected to enable operational integrations of global models of the atmosphere at resolutions close to 1 km, using tens of thousands of processors in the foreseeable future. ...
