Budapest's air quality faces significant winter challenges, with residential wood and coal burning combining with heavy traffic on the Pest ring roads to elevate PM2.5 and NO₂ during cold anticyclonic periods. The Danube river corridor provides ventilation on westerly winds, while the Buda hills on the western bank create topographic variation in pollution exposure across the city.
