摘要
本文利用飞机航测AMDAR数据和北京市环境保护局监测站点逐时观测数据,对2016年12月15到12月22日一次重污染过程的污染形成和消散原因做了分析。结果表明:本次污染过程表现为前期逐渐积累,高浓度保持和快速消散的特点,形成此次重污染过程的天气成因是北京地区受均压场和弱高压影响,大气层结稳定,伴有低空逆温形成,污染物垂直扩散能力弱。

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.
