Alessandria's air quality faces the Po Valley's enclosed flat basin, with vehicle traffic on the A7 and A26 motorways and surrounding manufacturing and logistics industry contributing local sources. The Tanaro-Po river confluence provides limited ventilation, while the flat Po plain's persistent winter anticyclones trap emissions under extended inversion periods and the Ligurian Apennines to the south create partial topographic enclosure throughout the year.
