摘要
本文对广州市2017年9月26-28日的环境空气污染过程的空气质量和气象条件特征进行分析,发现该污染过程具有区域性特征,与天气形势的变化关系密切,过程中925 h Pa和850 h Pa高压中心叠加了暖中心,同时存在贴地气温逆温和露点逆温,逆温与高压南侧的东南气流有关。
This paper analyzed the air quality and meteorological characteristics of air pollution in Guangzhou from September 26 to September 28. It was found that the pollution process hadregional characteristics and had closely relationship with the change of weather conditions. In the process, the warm centers were superimposed on the high pressure centers of 925 h Pa and 850 h Pa, and the inverted temperature and the inverse temperature of the dew point existed at the same time. The temperature inversion was related to the southeastern airflow from the south of the high pressure.
