Taichang, nestled within Gansu Province in northwestern China, occupies a geographically complex position. Located at coordinates 35.4002°N, 107.7739°E, the city sits on the northeastern edge of the Loess Plateau, a vast expanse of wind-deposited silt. This plateau terrain, characterized by gullies and ridges, significantly influences local wind patterns and sediment dispersal, impacting air quality. The surrounding landscape is dominated by semi-arid grasslands and agricultural lands, primarily focused on grain production. Taichang’s elevation, approximately 1600 meters above sea level, contributes to thinner air and potentially greater UV radiation, but also influences temperature inversions. While not directly adjacent to a major body of water, the city lies within the Wei River basin, meaning agricultural runoff and potential dust from the riverbed can affect air quality. The urban-rural gradient is relatively sharp; Taichang is a small city with a population of just over 13,000, surrounded by sparsely populated agricultural areas. Industrial activity is limited, but regional industrial belts further east, particularly those related to energy production and heavy industry, can contribute to transboundary pollution events. The Loess Plateau’s inherent susceptibility to wind erosion is a key factor in particulate matter concentrations.
Taichang experiences a pronounced continental climate, resulting in significant seasonal variations in air quality. Spring (March-May) often sees increased dust storms originating from the Gobi Desert and the Loess Plateau itself, dramatically elevating particulate matter levels. These storms are exacerbated by strong winds and relatively dry conditions. Summer (June-August) brings some relief, with occasional rainfall helping to suppress dust, but increased agricultural activity – harvesting and irrigation – can contribute to localised emissions. Autumn (September-November) is generally considered the most pleasant time of year for air quality, with calmer winds and clearer skies. However, the onset of heating season in late autumn can lead to increased coal combustion for residential heating, raising levels of sulfur dioxide and particulate matter. Winter (December-February) is the most challenging period. Cold temperatures create strong temperature inversions, trapping pollutants near the ground. Snowfall is infrequent, meaning pollutants aren’t efficiently scavenged from the atmosphere. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit outdoor exposure during spring and winter. Months to favour for outdoor activity are September and October. Monitoring wind direction is crucial; winds from the east often carry pollutants from regional industrial areas.
