The Zone of Discontinuity Between the Land and Sea Breezes and Its Importance to Southern California Air-Pollution Studies

Abstract

The effect of the discontinuity in the wind field between land and sea breezes has been studied by means of analysis of meteorological and chemical data associated with a particular pollution attack. Observational evidence indicates that there are periodic vertical eddy motions associated with the discontinuity. Variations in air-pollution concentrations are thought to be due to the location, in space and time, of pollution-stagnation areas, modified by the intrusions of air from aloft.
