Myski, nestled in the heart of southwestern Siberia within Kemerovskaya Oblast’, occupies a geographically complex position. The city is situated on the banks of the Tom’ River, a significant waterway flowing northwards, at an elevation of approximately 180 meters. This location within the West Siberian Plain contributes to a relatively flat terrain, though gently undulating hills are present in the surrounding areas. Historically, Myski’s development was intrinsically linked to the mining of iron ore, and it remains a key industrial centre, particularly for ferrous metallurgy. This industrial activity, concentrated around the city, is a primary determinant of its air quality. The surrounding landscape is a mix of coniferous forests – typical of the Siberian taiga – and agricultural land, primarily used for grain production. The urban-rural gradient is relatively sharp; transitioning quickly from industrial and residential areas to expansive forested regions. The Tom’ River, while providing a water resource, can also contribute to localised humidity and potential temperature inversions, trapping pollutants. The prevailing winds, generally from the southwest, can carry emissions from industrial sources across the city, impacting air quality for residents. The city’s position within a river valley further exacerbates the potential for pollutant accumulation.

Myski experiences a distinctly continental climate, resulting in significant seasonal variations in air quality. Winter (November to March) sees the most challenging conditions. Low temperatures create stable atmospheric layers, trapping emissions from heating systems and industrial processes. Snow cover reflects sunlight, reducing dispersion, and temperature inversions are frequent. February and March are typically the worst months. Spring (April-May) brings a gradual improvement as temperatures rise and precipitation increases, washing away some pollutants. However, snowmelt can initially lead to increased runoff carrying contaminants. Summer (June-August) generally offers the best air quality, with higher temperatures promoting dispersion and prevailing winds carrying pollutants away. However, periods of calm weather can still lead to localised build-up. Autumn (September-October) sees a deterioration as heating systems are reactivated and atmospheric stability returns. October is often marked by fog, further reducing visibility and trapping pollutants. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit strenuous outdoor activity during winter and autumn. Monitoring wind direction is crucial; avoid exercising downwind of industrial areas. Increased ventilation indoors during summer months can help mitigate indoor pollution.
