Abstract
In this paper, the atmospheric circulation characteristics, the causes of pollution formation and dissipation during a heavy pollution process from December 15 to December 22, 2016 were analyzed based on AMDAR data from aircraft and hourly observation data from the monitoring station of Beijing Environmental Protection Bureau. The results showed that the pollution process is characterized by gradual accumulation, high concentration and rapid dissipation. The weather cause of the heavy pollution process is that the atmospheric junction is stable under the influence of the homogeneous pressure field and weak high pressure, accompanied by the formation of low-level temperature inversion, and the vertical diffusion ability of pollutants is weak.
