In recent years, ground-level-ozone（O） pollution in urban areas in the Bohai Rim has attracted wide attention. Based on the analysis of the spatiotemporal distribution characteristics of O concentration in Dongying, a representative city in the Bohai Rim from 2017 to 2022, the effects of meteorological factors and sea-land breeze circulation on O concentration were evaluated. The results showed that： ① From 2017 to 2022, the annual assessment value of O concentration in Dongying showed a fluctuating upward trend, and the pollution days with O as the primary pollutant increased.

- Meteorological conditions significantly influence the occurrence and evolution of complex atmospheric pollution, specifically particulate matter (PM) and ozone (O), necessitating the development of pollution meteorological condition indexes through statistical and deep learning methods.
- Analysis of pollution data from summer 2021 revealed that central and eastern China's pollution conditions were worse in the north compared to the south, with the highest levels in June and the lowest in July, indicating a pattern of increasing "double high" pollution when specific index thresholds were exceeded.
- Improvements in meteorological conditions contributed to a notable decrease in PM concentrations across regions, with an average reduction of nearly 58.5%, while O conditions worsened in the south, particularly in the Yangtze River Delta, leading to an overall
