Abstract

Abstract

In 2022， the number of days with ozone exceeding the standard in Qingyang， the core area of Longdong large-scale energy and chemical base， increased sharply. In this paper， a typical ozone pollution process last from June 23rd to 25th was selected as the case. Based on the WRF model and HYSPLIT4 model， the meteorological causes and potential ozone source areas were analyzed in combination with pollution characteristics and topography， to provide a reference for ozone pollution control in the Loess Plateau of Longdong. The results showed that： 1） On June 24th， the high altitude of Qingyang was behind the trough， and the airflow sank， which was not conducive to the vertical diffusion of pollutants. The maximum concentration of O₃_8 h reached 174.5 μg/m³ during the day； in the early morning of June 25th， the phenomenon of high O₃ concentration occurred， which was mainly influenced by the south wind and downward flow. 2） During the pollution period， the overall concentration of PM_2.5was low， but on June 24th and 25th， the overall concentration of PM_2.5 increased， which may be affected by the accelerated photochemical reaction. On June 24th， sufficient NO₂ accelerated the local O₃ production. 3） According to meteorological factors， the concentration of O₃ in Qingyang was most affected by relative humidity， followed by temperature and air pressure. 4） The results of air mass trajectory clustering and potential source analysis show that the regional pollution transmission and local generation in Guanzhong Plain are the main reasons for this ozone pollution in Qingyang， and the pollution transmission contributes more.
