The author gives a brief review of the meteorological aspects of air pollution, as a background for the implications they have on biological and medical effects. The meteorological factors are important because they determine the rate of diffusion of pollutants and, thus, the concentrations of contaminants in the air, given the configuration and intensity of the sources. The two factors which enter are the wind velocity and the vertical temperature gradient or lapse rate. The wind speed enters double, first as a simply transport factor, determining the volume of air into which the pollution initially is injected, and second as a control of the turbulent diffusion, both horizontal and vertical. The stronger the wind, the more energy goes into turbulent fluctuations which spread the pollution literally. The vertical temperature gradient controls the up and down motions of the air and, thus, the rate at which diffusion in the vertical direction occurs.
