摘要
2018年1月19日-20日大连市发生一次空气质量重污染过程,本次污染主要受外来传输影响较大,是一次典型的传输影响导致的重污染过程。本研究利用大气自动监测常规站数据、超级站数据、3D可视激光雷达数据和HYSPLIT气流后向轨迹模型的模拟结果等相结合,初步分析了本次重污染的特征及污染原因,以期为日后的污染原因判断及重污染预报工作提供一定的基础依据。
A heavily polluted air quality process appeared in dalian city during January 19 -20, 2018. The pollution was mainly influenced by external transmission, which was a typical transmission effect heavy pollution process. In this study, by using routine atmosphere automatic monitoring station data, super station data, 3 d visual laser radar data and simulation results of HYSPLIT backward trajectory model of air flow, the characteristics of the heavy pollution and pollution reasons were analysed. The research results provided scientific theoretical basis for the causes of pollution and heavy pollution forecast in the future work.
