Surface ozone (O₃) pollution has become one of the top environmental issues in recent years around the world and can be influenced by meteorological processes on multiple scales. Understanding the meteorological mechanism and contributions of O₃ pollution is of great importance for O₃ mitigation. In this study, we explored the impacts of meteorological conditions on O₃ concentrations in a coastal city in Southeast China, with a particular focus on O₃ pollution episodes inspringtime. A significant increase in the O₃ pollution ratefrom 2015 to 2020 was observed (41.7% year⁻¹) and the seasonal characteristics of O₃ concentrations showed a two-peak pattern. We selected 12 pollution episodes during the springtime of 2015 to 2020 and identified four dominant synoptic weather patterns (SWPs) that could cause O₃ pollution. The local meteorological conditions and vertical dynamic structures under different SWPs were analyzed. The results showed that high O₃ levels tend to be associated with high temperature, weak wind, low relative humidity, and deep vertical sinking motion. We also established a quantitative linkage between the O₃ values and meteorological factors. Based on meteorological conditions, 60.8~80.8% of the variation in O₃ can be explained.
