Evansville's air quality reflects the Ohio River valley's topographic tendency to trap industrial and vehicle emissions under inversions, with the surrounding Indiana and Kentucky hills limiting dispersal on calm days. Coal-fired power plants in the surrounding Tri-State energy corridor and vehicle emissions from the Lloyd Expressway are the primary sources, while the Ohio River valley's characteristic winter inversion problem concentrates emissions from the regional industrial corridor during extended calm anticyclonic periods.
