A mathematical model for air pollution control in urban areas

A new mathematical model for air pollution control in urban areas is proposed. Urban air pollution is the result of the accumlation of pollutant, caused by the transition of the wind fields. In the present paper, the feature of urban air pollution phenomena is discussed first. Secondly, a new model structure is proposed which treats the concentration of pollutant in the background separately from the whole pollutant. Finally, an example of numerical simulation based upon the proposed model is shown.
