The most crucial atmospheric phenomenon is the change of atmospheric pollutant from gaseous status into the particle shape. To study about advection and diffusion of environmental air pollutants emitted by an area resource in an urban region, a numerical model is being framed in the present article. The numerical solution of outlining differential equations is carried out using Crank-Nicolson implicit technique. The examination of results being done for the dispersion of pollutant in an urban region for atmospheric stable state as well as neutral state in presence and absence of mesoscale wind in various meteorological conditions.
