Description:
A statistical map-typing procedure was used to stratify regional weather patterns over a 800-km radius area centered on St. Louis. It was intended for application to air pollution studies. Seasonal weather types were obtained for 850-mb height patterns and for geostrophic wind patterns based on surface pressure gradients for the four-year period 1973 through 1976. A total of 21 separate weather map types were identified for the 850-mb level synoptic flow, and a total of 36 map types were identified for the geostrophic wind flow. To show the relationships between the synoptic weather types and air quality, statistical correlations were calculated between the daily map types and observed air quality data using 03, CO, total suspended particles, sulfate, and nitrate concentrations from the 1975-1976 St. Louis RAPS program.
