Jingping, Shanxi Province, China, occupies a geographically complex position within the Loess Plateau, a vast expanse of eroded sediment dominating much of north-central China. Situated at approximately 39.52°N, 112.28°E, and an elevation of around 1,500 meters (4,921 feet) above sea level, the city experiences a continental climate heavily influenced by its plateau setting. The surrounding landscape is characterized by rolling hills and deep valleys, sculpted by centuries of wind and water erosion. This terrain significantly impacts air circulation; valleys can trap pollutants, while the surrounding hills offer limited escape routes for emissions. Jingping’s proximity to the Taiyuan industrial belt, a major hub for coal mining, heavy industry, and manufacturing, is a critical factor in its air quality challenges. Agricultural zones, primarily focused on wheat and corn cultivation, contribute to particulate matter through seasonal burning practices and soil disturbance. The urban-rural gradient transitions relatively quickly, with agricultural land and smaller villages bordering the city limits. The Yellow River, though not directly adjacent, flows within a reasonable distance, influencing regional weather patterns and potentially impacting the dispersion of pollutants. The city’s location within a rain shadow area, receiving less precipitation than regions further east, exacerbates the problem, as rainfall acts as a natural air cleanser. The Loess Plateau’s porous soil also limits the retention of moisture, further reducing natural cleansing processes. This combination of topography, industrial proximity, and climatic conditions creates a challenging environment for maintaining clean air.

Jingping’s air quality follows a distinct seasonal pattern dictated by meteorological conditions and human activity. Winter (November – February) consistently presents the most challenging period. Cold temperatures lead to frequent temperature inversions, where a layer of warm air traps cooler air and pollutants near the ground, resulting in stagnant air and elevated particulate concentrations. Residential coal burning for heating significantly contributes to this problem, alongside industrial emissions. Spring (March – May) brings a gradual improvement as temperatures rise and winds increase, though dust storms originating from the Gobi Desert can periodically impact air quality, depositing fine particulate matter. Summer (June – August) generally sees the best air quality due to increased rainfall, which washes pollutants from the atmosphere, and stronger winds that disperse emissions. However, occasional periods of high humidity and stagnant air can still lead to localized pollution episodes. Autumn (September – October) marks a transition period, with decreasing rainfall and cooler temperatures. Agricultural burning, a common practice for clearing fields, contributes to increased particulate matter during this time. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during winter and early spring, limiting outdoor exposure and using air purifiers when possible. During periods of dust storm activity, wearing a high-quality mask is recommended. Summer generally offers the most favourable conditions for outdoor activities, but monitoring local air quality reports remains prudent. The monsoon patterns, though less pronounced than in southern China, still influence regional weather and contribute to the seasonal variations in air quality.
