Prediction of Atmospheric Dispersion of Gaseous Pollutants in Inversion Break-up Fumigation

摘要：

An improved model based the Chinese regulatory recommended Gaussian model for a threedimensional downwind spatial dispersion simulation of gaseous pollutants in inversion breakup fumigation (IBF) while the maximum ground level concentration (GLC) occurred is presented.The validation of the model procedure was conducted by comparing the simulation results with observation data in a southwest China area.Better agreements were obtained in comparison with conventional algorithm widely used in China.The outputs of the procedure were presented in a graphical form.According to the case study,the maximum GLC in IBF condition (Cfm) is several times as large as that in neutral atmospheric stability condition (Cm)and the range of Cfm/Cm＞1 is extended about 66 times as far as the effective height of emission.Wind direction is the primary factor that affects air pollution in IBF condition.
