Influence of Weather System of Different Scales on Pollution Boundary Layer and the Transport in Horizontal Current Field

Abstract

Atmospheric boundary layer is influenced not only by the ground surface but also directly by the weather system of different scales.Based on both the data from the three sites of the laser radars which all were situated along the south-north direction of Beijing city,and that from the ground surface particle monitors, a severe pollution progress was selected for scenario analysis,to study the influence of weather system of different scales on the particle boundary layer and analyze the dynamic (kinetic) change of the transport of the particle concentration in the boundary layer.The formation causes of severe pollution in Beijing area were given.The boundary layer research of the territorial atmospheric pollution would help to further understand the mechanism of the formation of the terrritorial and urban environment pollution.
