Abstract

In a terrain of high complexity, such as mountain regions or local scale building structures, the topography is characterized by irregularities covering a wide range of dimensions and/or sizes. The irregularities can influence considerably the pressure gradients and induce mechanical effects on the wind systems. The air/ground interaction in terms of energy exchange can become highly variable due to rapid changes on surface orientation or altitude or even land use. As a sequence the wind system evolution is usually of multiscale character both in space and time especially in the case of thermally developed winds. A pollutant release advected by such multiscale wind
