Bucharest's air quality faces seasonal challenges, with winter wood and coal burning combining with heavy diesel traffic on the ring roads to elevate PM2.5 and NO₂ significantly during cold periods. The flat Wallachian plain provides some wind dispersal, though calm anticyclonic conditions in winter allow emissions to accumulate across the low-lying metropolitan area.
