Analysis and Simulation of a Serious Heavy Regional Air Pollution Process

To study the regional air pollution and its causes of pollution,a serious heavy air pollution process was analyzed and simulated.Results show that pollutants cumulate for a long time and form heavy pollution with the high pressure and low weak pressure in the air,and regional air quality turns good in the influence of front.A meso-scale meteorology model is used to simulate relative meteorological factors. Simulation results can explain the mechanism of heavy pollution in northern parts of China.
