Positioned in the Ostrava coal basin near the Polish border, Karviná experiences air quality shaped chiefly by coal-mining legacy emissions trapped by the basin. The Moravian-Silesian Region 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.
