A practical model for the dispersion of skewed puffs

Abstract

A practical puff model based on the Monin-Obukhov similarity theory is presented. The model uses approximate solutions for the dispersion of a cloud of passive contaminant released from instantaneous sources and where particular importance is given in describing the interaction between wind shear and vertical diffusion. The model performances are evaluated against tracer ground-level concentrations released near the ground and at a height of 115 m. -Authors
