Varese's air quality faces the Po Valley's enclosed flat basin challenge in the Prealpine lake district, with vehicle traffic on the A8 motorway and surrounding manufacturing industry contributing local sources alongside the Malpensa Airport's significant aviation NOₓ. The surrounding Prealpi Varesine create topographic variation, while the lake district's breezes provide some local ventilation and the Po Valley winter anticyclone creates extended inversion episodes affecting all of Lombardia.
