Abstract:

In recent years, with the urban construction and economic development, the problem of aerosol pollution is becoming increasingly serious. Especially for foggy weather in urban areas, aerosol particles form a primary pollutant. This calls for people’s concern to deal with the fog pollution problem for clean air. This paper focuses on the basic characteristics of aerosol particles and fog, including turbulent diffusion of aerosol particles, chemical transformation and dynamical characteristics. In addition, a detailed investigation on the aerosol transport problem in China and other countries is made, and the direction of the studies is discussed. 

Key words: pollution fog; aerosol particles; transport; chemical transformation; dynamical characteristic
