Physical Modeling of Gas Pollutant Motion in the Atmosphere

A closed form solution for pollutant dispersion in atmosphere considering nonlocal closure of the turbulent diffusion

Atmospheric air pollution turbulent fluxes can be assumed proportional to the mean concentration gradient. This assumption, along with the equation of continuity, leads to the advection-diffusion equation. Moreover, large eddies are able to mix scalar quantities in a manner that is counter to the local gradient. In this work we present an analytical solution of the three-dimensional steady stat...

Simulation of Dispersion of Polluted Gases in Atmosphere

A computer program was developed to predict the dispersion of gas pollutant in the atmosphere. This program relies on puff method, and in order to consider the wind shear effects, the program has the ability to consider the complete dynamic and unsteady atmospheric conditions. Plume rise of hot pollutants due to buoyancy effects was also considered. The program has the capacity to perform the r...

Dispersion in the Atmosphere of a Pollutant Drifting at the Sea Surface; Galerne Project

Within this project, Meteo-France is in charge of evaluating the transport of the patch of pollution at the sea surface and the atmospheric dispersion of the chemical substance linked to its evaporation. A modelling system has been settled, which consists of the coupling of two models: The first one, MOTHY, is Meteo-France operational drift forecast system in case of marine pollution. It is a t...
