Kroměříž, nestled in the Zlínský Kraj of the Czech Republic, occupies a strategically significant position within the Upper Moravian Vale. The city is situated on the banks of the Morava River, at an elevation of approximately 220 meters, contributing to a relatively flat, fertile landscape. This location, historically advantageous for trade and agriculture, now presents unique air quality challenges. The surrounding terrain is characterized by gently rolling hills, transitioning into the foothills of the Carpathian Mountains to the east. To the west lies a more open agricultural landscape, dominated by arable land. While not directly within a major industrial belt, the broader Zlín region has a history of manufacturing, and prevailing westerly winds can transport pollutants from these areas towards Kroměříž. The urban-rural gradient is relatively sharp; the city centre gives way quickly to farmland and forested areas. The Morava River, while providing a scenic amenity, can also contribute to localized humidity and temperature inversions, trapping pollutants near the ground. The city’s compact urban form, with a mix of older residential areas and newer developments, influences local wind patterns and pollutant dispersion. Understanding these geographical factors is crucial for assessing and mitigating air quality concerns in Kroměříž.

Kroměříž experiences a temperate continental climate, resulting in distinct seasonal air quality patterns. Winter (December-February) typically sees the poorest air quality, driven by increased use of solid fuel heating – coal and wood – for residential purposes, coupled with frequent temperature inversions that trap pollutants. Calm, stable atmospheric conditions exacerbate this issue. Spring (March-May) brings gradual improvement as temperatures rise and heating demand decreases, though occasional stagnant air can still lead to elevated particulate matter. Summer (June-August) generally offers the cleanest air, benefiting from prevailing winds and increased atmospheric mixing. However, prolonged heatwaves can trigger ground-level ozone formation. Autumn (September-November) sees a return to poorer conditions as heating systems are reactivated, and damp, foggy conditions can trap pollutants. October and November are particularly concerning. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit strenuous outdoor activity during winter and autumn. Monitoring pollen levels is also important in spring. Avoiding peak traffic hours and staying informed about local air quality reports are recommended year-round. The Morava River’s influence on humidity can also contribute to the formation of fog, which can worsen particulate matter concentrations.
