Olomouc's air quality reflects the Moravian plain position in the Morava river valley, with vehicle traffic on the R35 expressway and surrounding manufacturing and university research industry contributing local sources. Winter residential wood and coal burning generates elevated PM2.5, while the flat Haná plain generally allows reasonable wind dispersal on most days and the surrounding Jeseníky and Carpathian ranges create topographic variation throughout the year.
