Abstract: A variable-resolution global shallow-water model has been developed. The scheme makes use of a two-time-level semi-implicit semi-Lagrangian discretization, and the variable-resolution grid is composed of a basic global ...

Abstract: A vector semi-Lagrangian semi-implicit two-time-level finite-difference integration scheme for the shallow water equations on the sphere is presented. A C-grid is used for the spatial differencing. The trajectory-centered ...

Abstract: his article describes the main features of the Brazilian Global Atmospheric Model (BAM), analyses of its performance for tropical rainfall forecasting, and its sensitivity to convective scheme and horizontal resolution. ...
