The National Air Pollution Potential Forecast Program
Abstract
Air Pollution Potential (APP) is definable as a measure of the inability of the atmosphere to adequately dilute and disperse pollutants emitted into it based on values of specific meteorological parameters of the macroscale features. To elineate areas on the macroscale in which high APP has the greatest probability of occurring, a stagnation index has been developed independent of mixing height and transport wind speed data. The associated stagnation conditions are usually manifested by stable stratification, weak horizontal wind speed components and little, if any, significant precipitation. We describe the numerical and subjective means by which stagnation areas are delineated, mixing height and transport wind speed calculated, and how high APP conditions are transmitted to our users via facsimile and teletypewriter.
