Definīcija:dispersion model.A mathematical representation and solution of the physical processes that result in the spread of pollutants in the atmosphere.The phenomenon of direct interest in predicting the dispersion of pollutants is turbulent diffusion.Consequently,dispersion models are sometimes called diffusion models.However,turbulent diffusion and diffusion models are misnomers.The spreading is really not due to a "diffusion" phenomenon such as results from molecular collisions but rather is a result of the rapid,irregular motion of lumps of fluid(called eddies)in turbulence
