Asti's air quality faces the Po Valley's enclosed flat basin, with vehicle traffic on the A21 motorway and surrounding wine and agri-food industry contributing local sources. The flat Piedmont plain's persistent winter anticyclones trap emissions under extended inversion periods, while the Monferrato hills to the east provide marginally better ventilation on easterly wind days and summer Po Valley ozone adds a significant warm-season dimension.
