WINDS, STABILITY, AND TWENTY-FOUR HOUR SULFUR DIOXIDE CONCENTRATIONS IN METROPOLITAN SAINT LOUIS
Abstract
A study of the relationships between wind, vertical temperature data, and twenty-four hour sulfur dioxide concentration data, collected from December 5, 1963 to February 28, 1963, was made. The sulfur dioxide samples were collected at twenty sampling sites in the St. Louis metropolitan area. The sulfur dioxide concentrations were related to the stability categories and wind direction. An analysis of the vertical temperature structure, recorded by the thermal sensing units on a TV tower, showed the 249-452 feet layer to be more unstable than the 127-249 feet layer when hourly frequencies of the stability categories were considered. An atmospheric stability, topography, and sulfur dioxide relationship showed all sampling sites located above 500 feet mean sea level experienced maximum average stability-concentrations only during stable conditions in the 249-542 feet layer. There was no build-up in the sulfur dioxide concentrations indicated during the longer stable periods.
