High ground level concentrations are very often observed for plumes dispersing in convective boundary layers. As has been pointed out by Lamb (1978, 1979), Willis and Deardorff (1975, 1978) and Venkatram (1980), conventional Gaussian plume methods are inadequate for treating dispersion inside a convective boundary layer. This is because, convective boundary layers consists of large scale eddies, the updrafts and downdrafts. Transport processes due to these eddies cannot be expressed by simple gradient transfer hypothesis for which the Gaussian plumes are valid.
