摘要：

A three-dimensional plume model is applied to the transport of pollutants in the lower atmosphere. The model contains parameterizations for the vertical and horizonal diffusion coefficients based on the turbulent energy equation. While this parameterization works well for stable and neutral conditions it is expectedly inadequate for convective conditions. An empirical extension containing the influence of strong ambient convection on updraft and downdraft of the plume improves comparisons with field data from tall stacks.
