Pollutants distribution is analysed through mathematical model in which factors affecting pollutants are discussed. An analytical scheme for the dispersion of air impurities in the presence of mesoscale wind is formed. The developed mathematical model discusses about the dispersion of impurities transmitted from line source in the urban areas with the mesoscale wind. Here it is considered the eddy diffusivity as a function of vertical height as well as constant large-scale wind. we employ separation of variables, orthogonal property of Bessel function and the special function method.
