In order to investigate the sensitivity of ozone concentrations to future climate variations, a regional oxidant model was applied for future climate scenarios to two regions: one covering central California (San Joaquin Valley, Sierra Nevada mountains and the San Francisco Bay Area) and the other covering the midwestern and southeastern United States. Based on model calculations, the effects of increased temperature on ambient ozone concentrations results in an increase of the area of exceedances of the ozone air quality standard, a movement of the peak ozone concentration closer to the urban areas, and the resultant increase in the exposure of people to harmful levels of ozone concentrations. The calculations for California indicate that the maximum daily ozone concentrations may increase from 2 to 20% and the number of people exposed to hourly ozone concentrations in excess of the air quality standard may triple as a result of a temperature increase. Similar, although less dramatic, results were seen for the midwestern and southeastern applications.
