Abstract

Abstract The frequency distributions of daily suspended particulate values at two stations in Toronto have been examined, as well as the weekly and seasonal cycles. Using the wind at a height of 120 m (obtained from an anemometer mounted on a television tower in the downtown area), a meteorological interpretation of the variations in air quality is obtained. Using subsets of days when wind direction remained within designated sectors, it is found that the poorest air quality was associated with S-SSW winds, the best with N-NNE winds. An analysis of the surface synoptic weather patterns accompanying the 14 days with highest particulate values at the two stations revealed that most high values occurred with a warm SSW flow associated with an anticyclone located over the eastern United States.
