Topeka's air quality benefits from the flat Kansas Flint Hills prairie providing excellent natural wind dispersal, with prevailing southwesterly and northwesterly winds generally keeping readings at moderate levels in Kansas's state capital. Vehicle emissions from I-70 and I-470 are the primary local sources, while agricultural ammonia from the surrounding Kansas wheat and livestock farming landscape contributes secondary particulate formation, and summer ozone from regional Midwest vehicle and agricultural sources is the primary warm-season concern throughout the year.
