Jomboy Shahri, nestled within the Samarqand region of Uzbekistan, occupies a geographically significant position at approximately 39.6989° N, 67.0933° E. The city’s location, at an elevation of roughly 380 meters (1247 feet) above sea level, contributes to its generally dry climate and influences local air circulation patterns. Situated on the Zerafshan River plain, Jomboy Shahri benefits from fertile alluvial soils, supporting a surrounding agricultural landscape dominated by cotton cultivation and fruit orchards. This proximity to intensive agriculture introduces potential sources of air pollution, particularly from pesticide application and fertilizer use, though the scale is currently limited by the city’s small population. The Zerafshan River itself, while providing a vital water source, can also contribute to localized humidity and fog formation, impacting pollutant dispersion. The urban–rural gradient transitions relatively quickly, with agricultural fields and small villages characterizing the immediate periphery. Further afield, the rugged foothills of the Zeravshan mountain range rise to the north and east, creating a barrier that can trap pollutants under certain meteorological conditions, especially during periods of temperature inversion. While Jomboy Shahri isn't directly adjacent to major industrial belts, its regional position within Uzbekistan means it is connected to broader transportation networks, potentially exposing it to emissions from passing vehicles. The relatively flat terrain surrounding the city allows for efficient agricultural practices but also limits natural ventilation, potentially exacerbating air quality issues during stagnant weather.

Jomboy Shahri’s air quality experiences a distinct seasonal cycle dictated by its continental climate. Spring (March-May) often brings a noticeable improvement as warmer temperatures and increasing wind speeds facilitate pollutant dispersion. However, this period also coincides with the start of the agricultural season, potentially introducing localized spikes in air pollution from fertilizer application and field preparation. Summers (June-August) are typically hot and dry, with minimal rainfall and frequent periods of atmospheric stability. This can lead to the formation of temperature inversions, trapping pollutants close to the ground, particularly in the early morning hours. Dust storms, originating from the nearby Kyzylkum Desert, are also a recurring concern during the summer months, significantly degrading air quality. Autumn (September-November) sees a gradual cooling and increased precipitation, which helps to cleanse the atmosphere. However, agricultural burning, a traditional practice for clearing fields, can contribute to elevated particulate matter levels. Winter (December-February) is characterized by cold temperatures and frequent fog, especially in the mornings. The combination of low temperatures, limited wind, and fog creates ideal conditions for pollutant accumulation, leading to periods of reduced visibility and potentially compromised air quality. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during winter mornings and summer afternoons, limiting outdoor exertion and monitoring for any adverse health effects. Maintaining indoor air quality through ventilation and air purification can also be beneficial during periods of elevated pollution.
