Description
This article investigates the modeling of dust storm dispersion and its impact on air quality in the Surkhandarya region and Termiz city using differential equations. The study is based on the advection-diffusion equations, which were used to analyze the spread of PM10 and PM2.5 dust particles in the atmosphere. Local meteorological and environmental conditions specific to Termiz city — including wind speed, prolonged drought periods, and dust sources resulting from the desiccation of the Aral Sea — were taken into account.
The simulation results revealed that dust storms constitute one of the primary causes of air pollution in Termiz. Furthermore, practical recommendations are proposed for the early warning of dust storms and the enhancement of the air quality monitoring system.
