Edinger, J G

The meteorological factors which affect the concentration of air pollutants observed at ground level over and downwind of large urban complexes are discussed. They are subdivided into those due to: (1) transport, (2) diffusion, and (3) terrain effects. Examples are given showing how transport (wind) determines the length of time a given air parcel is exposed to the area source. Examples are also presented suggesting how diffusion by the eddying motions of the turbulent lower atmosphere leads to the progressive dilution of the air parcel with the surrounding atmosphere. It is indicated how terrain influences both wind and eddy diffusion, and how they have their own effect on the concentration of pollutants. Meteorological data requirements for describing the polluted wake from a large area source are described.
