Roles of Complex and Simple Terrain in the Estimation of Atmospheric Diffusion

摘要

The highly specialized yet integrated requirements for theory, numerical modeling, and field experiments have led to the organization of teams that incorporate different specialties around a shared objective. This paper attempts to establish a context for the dominant terrain effects including the role of vegetative cover. Some practical needs for a thorough understanding of terrain influence are explored, some of the phenomena that have been identified as complicating the transport and diffusion of pollutants are reviewed. A variety of methods that have been used to characterize the topography itself for atmospheric transport applications are reviewed. (ERA citation 07:051450)
