Abstract
The application of the Swiss Clean Air Act requires the use of dispersion models for air pollutants in the Prealps. This region is characterised by complex terrains with valleys, lakes and flat areas. This paper discusses the specific factors which influence -the dispersion of air pollutants in the pre-alpine areas. Examples from the Lugano region (south of the Alps) and the Reppisch Valley (south of Zürich) illustrate the relevance of the asymmetry of the valley’s cross-section, the effect of the combination of a valley and a lake, the importance of the accumulation process below stable layers and the occurrence of oscillating motions of air masses. The paper concludes with a brief overview of dispersion models which could be used in the pre-alpine region.
