A LAGRANGEAN MODEL OF AIR POLLUTANT DISPERSION
In a continuum interspersed by clean eddies, a polluted puff is released. It undergoes the same fate as the other eddies: it has a certain stability phase, it then disintegrates into smaller units which, in turn, decay after a certain lifetime and which, at the end of the cascading process, lose their macroscopic particle structure. These eddies interact with the clean turbulence elements. Lifetime, size, mobility, and position of the single air parcel are governed by stochastically assigned variables. A Monte Carlo approach follows the history of the puff-components from point- source to receptor.
