| Abstract: |
| In order to explore the temporal and spatial distribution characteristics of ozone and its impact on meteorological factors in Anhui Province, we use the ozone data and meteorological observation data of ambient air quality monitoring from 2017 to 2019, combined with HYSPLIT(Hybrid Single Particle Lagrangian Integrated Trajectory) model and PSCF( Potential Source Area Analysis), respectively evaluates the regional distribution of ozone pollution and the impact of meteorological factors on ozone concentration in Anhui province, and analyze the impact of regional transmission on ozone concentration in Anhui province. The results show that:from 2017 to 2019, the ozone concentration in Anhui province increased significantly, with a year-on-year increase of 12.2%. The second quarter (April, May and June) and the third quarter (July, August and September) are periods with relatively high ozone concentration. The results show that the air pollution mainly comes from the inner part of Anhui province, while the potential source distribution shows that the contribution of air pollution mainly comes from the midland (Hefei, Anqing, Ma’anshan, etc.), and other sources were mainly from Jiangsu and Shandong provinces. Ozone concentration is positively correlated with temperature and total solar radiation intensity, negatively correlated with precipitation and relative humidity, and has little correlation with wind speed.. The results show that the increase of ozone pollution in Anhui province is mainly due to the aggravation of local emissions, and the external transport may have a certain influence. In addition, the impact of high temperature and strong solar radiation will aggravate the degree of ozone pollution and lead to heavy pollution. |
