Yerevan's air quality reflects the Ararat Plain's enclosed basin at 990 metres surrounded by the Caucasus and Armenian Highlands, with vehicle traffic on surrounding expressways and the manufacturing, construction, and residential heating corridor generating elevated PM2.5 under persistent winter inversions. The Ararat Mountain backdrop creates dramatic topographic enclosure, while the Armavir Valley's channelled winds provide seasonal relief and Yerevan generally maintains moderate to elevated South Caucasus capital city readings throughout the winter months.
