Abstract

A semi‐implicit scheme, in which the time‐step is limited only by the advective criterion, is analysed and successfully tested in a fully compressible non‐hydrostatic mesoscale model.

A semi-implicit, semi-lagrangian algorithm suitable for the simulation of the dry, adiabatic, nonhydrostatic atmospheric dynamics is introduced and analysed. Height is used as vertical coordinate, without the customary terrain following normalization, thus resulting in a stable, robust, and efficien
