Development of Meteorological Computer Models

Abstract

The solution of present day atmospheric and environmental problems requires the treatment of highly complex physical and chemical systems. Exchange processes between the atmosphere and the Earth's surface covered with vegetation are important not only for the energy and water supply of the atmosphere, but also for the mass balance of most of the chemical species forming the air pollutants. The structure and power of atmospheric models applicable for simulating the atmospheric flow over mountainous terrain, the transport of air pollutants and their chemical transformation during the transport on a regional scale are described. Within the model described here, the uptake of chemical species by the soil and vegetation and the emission of chemical species by the plants are also taken into account. Some examples of simulations are discussed.
