POLLUTANT TRANSPORT IN COASTAL AREAS WITH AND WITHOUT BACKGROUND WIND

A three-dimensional meteorological model and a Lagrangian particle dis persion model are used to study the effects of a uniform large-scale w ind on the dispersion of a non-reactive pollutant in a coastal region with complex terrain. Simulations are carried out both with and withou t a background wind. A comparison between model results and measured d ata (wind and pollutant concentrations) indicates that the coupled mod el system provides a useful mechanism for analyzing pollutant dispersi on in coastal regions.
