Atmospheric Diffusion Studies Near a Lake Shore

Abstract

Experiments designed to measure atmospheric diffusion in transitional states have been carried out for several years over the western end of Lake Erie. The concept of diffusion in transitional states, both in general and for such a shoreline location, is described. The methods of data analysis which have been used are explained and their advantages and limitations outlined. Results of the experiments are presented in terms of Sutton's parameters n, Cz and Cy are generally larger than those which have been measured over more uniform sites. One experiment is described in detail to illustrate diffusion in a trasitional state which was due to the advection of warm air aloft.
