Dispersion and removal of pollutants during the passage of an atmospheric frontal system

Abstract

Abstract Results are presented from a numerical mesoscale modelling study of the effects of meteorological phenomena on the distribution of contaminants, both airborne and deposited onto the surface, arising from hypothetical idealized release episodes. An Eulerian transport/diffusion/removal model is coupled to the Meteorological Office non‐hydrostatic mesoscale model, with removal tuned to represent the wet deposition of pollutants likely to be emitted during a nuclear power station accident.
