Validation of a New Turbulent Parameterization for Dispersion Models in Convective Conditions

A new parameterization for turbulentdispersion in a convective boundary layer isproposed. The model is based on turbulentkinetic energy spectra and Taylor's diffusiontheory. The formulation, included in an advanceddispersion model, has been tested and comparedwith vertical and lateral dispersion schemesreported in the literature, using data from fieldexperiments. The application of a statisticalevaluation shows that the proposedparameterization has the best overall fit to the data.
