Behavior of Smokes and Agents during Variable Meteorological Conditions over Complex Terrain.

Abstract

A program was undertaken to develop a system of models for describing transport and diffusion of smokes and agents in complex terrain under time-varying meteorological conditions. The ulitmate goal is to provide the probabilities for observing concentration(point or path-integrated) above a specified threshold. Lidar cross-sections through smoke plumes were analyzed and a preliminary mehtod for estimating the likelihood of finding a clear path through the plume is discussed. The literature was reviewed to find a framework for generating the required small-scale concentration distribution. The concept of fractal dimension is shown to have considerable promise. An extensive literature review and bibliography on the subject of scaling, fractal dimension, and applications to atmospheric processes is included as an appendix. The report describes the research necessary to apply the identified concepts and to complete the desired system of models.
