ALPTHERM -A PC BASED MODEL FOR ATMOSPHERIC CONVECTION OVER COMPLEX TOPOGRAPHY

Olivier Liechti, Bruno Neininger

Abstract


Topography is a key element for regionalized gliding forecasts.  Its detailed consideration in modelling atmospharic convection is possible with todays personal computers.  The presented PC-based model <<ALPTHERM>> produces regionalized forecasts of the parameters important for gliding.  Used as a simulator <<ALPTHERM>> illustrates effects like the convective enhancement of low-lying inversions in mountain valleys and the volume effect.  Quantitative information of the mixing process in the boundary layer is also obtained for complex topography.
