Abstract

In this paper, to describe the effects of a tall forest canopy on the structure of the atmospheric boundary layer, a parameterization scheme proposed by Schilling [1] is applied within the framework of an atmospheric model based on finite elements. The main advantage of the scheme is that the dynamic and thermodynamic effects of the forest cover can be satisfactorily simulated using only coarse resolution in the numerical model. This makes it possible to study the meteorological phenomena in a simpler way, in comparison with the conventional approach. The advantages of using this approach in numerical models are shown by numerical simulations with a twodimensional model of finite elements for a flat terrain that is uniformly covered with a homogeneous forest canopy consisting of coniferous trees of about 20 meters in height. The simulation results reproduce some of the wellknown meteorological phenomena in forest areas, for example, a reduction in the wind speed in the forest cover.
