Weak atmospheric dilution capability is a key factor leading to the frequent occurrence of serious air pollution. This study aims to analyze the mixing layer dilution capability of the atmosphere and to quantify the mixing layer PM2.5 transport flux. Our results showed the main controlling factors during the transition and heavy polluted period in Beijing. The results help in understanding the causes of air pollution and making decisions on prevention and control of air pollution.
