Abstract Local variations in the summertime mixing height over metropolitan St. Louis, Missouri, are examined in order to evaluate the dynamical and thermodynamical influences of an urban area. Case studies employing aircraft, lidar, pilot balloon and radiosonde data from Project METROMEX show variations in the height of a temperature inversion which caps a deep mixing layer. A dome-like lifting of the inversion structure occurs over the urban-industrial center with subsidence of the inversion layer at the perimeter of the metropolitan area. The maximum amplitude of the dome occurs shortly after mid-day, suggesting that thermal influences are primarily responsible.
