Abstract

The Planetary Boundary Layer (PBL) constitutes the interface between the atmosphere and the Earth's surface. Transport processes through the PBL determine the hydrological and energetic cycle of the atmosphere to a considerable degree. Theory concerning this role of the PBL is provided as well as information on the states of the PBL and other important processes (such as pollution dispersion).

Objective

Theory and practical information concerning the understanding of the Planetary Boundary Layer. Discussion of the relevant processes (turbulent transport, forcing) and typical states of the PBL. Comparison of idealised vs real surface characteristics (as for example over complex topography). In parallel to developing the above themes concerning the PBL, dispersion of air pollutants is discussed as a practical application.

Content

- Introduction - Turbulence - statistical tratment of turbulence, turbulent transport - conservation equations in a turbulent flow - closure problem and closure assumptions - scaling and similarity theory - spectral characteristics - ideal vs real boundary layer characteristics - basics for air pollution modeling
