雾对大气污染物迁移扩散的影响

The Effects of Fogs on the Transport and Diffusion of Air Pollutants.

从雾形成和发展过程中热力和动力特征的变化,分析了大气污染物在雾天气下的迁移扩散和清除过程。表明,在某些情况下,雾对污染物有明显的清除作用,在某些情况下,雾可以造成地面高浓度污染。

From the changes of thermodynamic and dy-namic characteristics in the process of formation and development of fogs, the transport, difusion and scavenging processes of air pollutants in the foggy weather were investigated. The results show that, on some conditions, fogs can effectively scavenge gaseous pollutants, while on other conditions, fours may cause severe pollution on the ground.
