A Theoretical Study of Meteorological Effects on the Dispersion of Atmospheric Contaminants in the Coast Environment.

Abstract

Present numerical models describing pollutant diffusion employ two main approaches to the problem: gaussian bivariate distributions and numerical simulations of diffusion. The thesis examines numerical models of each method. The governing equations are discussed, with basic assumptions which permit reasonable simplifications to be made. Results of both models are examined qualitatively to describe patterns of marine-layer pollutant dispersal. Calculations from both models reveal wind velocity to be the most critical atmospheric characteristic controlling dispersion. Rates of spreading are also closely related to other measurable meteorological properties such as thermal stability and mixing depth. (Modified author abstract)
