Sortöbe, nestled within Zhambyl Province in Kazakhstan, occupies a geographically significant position in the country’s southeastern region. Located at coordinates 42.8600° N, 75.2300° E, the city sits within a broad, gently undulating steppe landscape, characteristic of central Asia. The terrain is relatively flat, with a gradual rise towards the foothills of the Tian Shan mountains to the east, influencing local wind patterns. Sortöbe’s elevation, approximately 1000 meters above sea level, contributes to cooler temperatures and a drier climate compared to lower-lying areas. The city is not directly adjacent to any major bodies of water, though the nearby Talas River plays a role in regional irrigation and microclimates. Surrounding Sortöbe are extensive agricultural lands, primarily dedicated to wheat and barley cultivation, alongside smaller areas of livestock farming. While not a major industrial hub itself, Sortöbe functions as a regional service centre for the surrounding agricultural zone. The urban-rural gradient is pronounced; the city represents a concentrated area of population and infrastructure amidst a vast expanse of rural farmland. This proximity to agricultural activity, coupled with potential dust from the steppe, significantly impacts local air quality, particularly during harvest seasons and periods of strong wind. The prevailing winds, generally from the northwest, can transport pollutants from distant sources, further complicating the air quality profile.

Sortöbe experiences a continental climate with distinct seasonal variations that profoundly affect air quality. Spring (March-May) sees increasing agricultural activity, leading to a rise in particulate matter from field preparation and potential burning of crop residue. Winds are often strong, exacerbating dust storms. Summer (June-August) is generally drier, with clearer skies, but temperatures can rise, promoting the formation of ground-level ozone. The lack of significant rainfall means pollutants accumulate. Autumn (September-November) is often the most challenging period. Harvest season generates substantial dust and smoke from burning agricultural waste, creating periods of poor visibility and respiratory irritation. Temperature inversions become more frequent, trapping pollutants near the ground. Winter (December-February) brings cold temperatures and stable atmospheric conditions. Heating with coal and wood in residential areas becomes prevalent, contributing to elevated levels of particulate matter and sulfur dioxide. Snowfall can temporarily cleanse the air, but also creates ‘black snow’ contaminated with combustion byproducts. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit outdoor activity during autumn and winter. Spring and summer offer better air quality, but monitoring remains crucial due to agricultural emissions. Months to avoid prolonged outdoor exposure are October and November.
