A Skewed Puff Model
A practical puff model based on the Monin-Obukhov similarity theory is presented. The model (named SPM: Skewed Puff Model) utilises approximate solutions proposed by van Ulden for the dispersion of a cloud of passive contaminant released from a source near the ground and where particular importance is given in describing the interaction between wind shear and vertical diffusion. The model can be applied routinely using as input simple ground-level meteorological data acquired by an automatic network.
The concentrations calculated with the model are compared with an experimental data set for a relatively tall source.
