摘要:
利用NCEP再分析、资料及空气自动监测站和micaps探空等资料，运用天气学分析和统计方法，对2019年9月24日至10月1日广西玉林一次臭氧污染过程的天气形势、热力动力特征及气象条件进行了分析。结果表明，受副高控制及台风外围下沉气流影响，高低层一致偏北风的稳定天气形势导致高温晴朗天气持续，利于臭氧浓度增加；垂直方向上多层逆温，扩散条件差，导致污染物在低层积聚；臭氧浓度与相对湿度、最大风速呈负相关，与日照时数呈正相关。
Abstract:
Based on the NCEP reanalysis data, air automatic monitoring station data and micaps sounding data, using meteorological analysis and statistical methods, the weather situation, thermodynamic characteristics and meteorological conditions of an ozone pollution process in Yulin, Guangxi from September 24 to October 1, 2019 were analyzed. The results show that:due to the control of the sub-high and the sinking airflow around the typhoon, the stable weather potential of northerly winds in the upper and lower layers leads to the persistence of high temperature and clear weather, which is conducive to the increase of ozone concentration; Multi-layer temperature inversion leads to poor diffusion conditions, resulting in the accumulation of pollutants in the lower layer; Ozone concentration was negatively correlated with relative humidity and maximum wind speed, and positively correlated with sunshine hours.
