Positioned on hills above the Yantra river gorge, Veliko Tŭrnovo experiences air quality shaped chiefly by vehicle traffic and residential wood-burning in the hill town. The Veliko Tarnovo terrain plays a role in how pollutants move through the area, with breezier conditions typically dispersing emissions faster than the still, settled spells that let them accumulate.
