| description | Ozone (O<sub>3</sub>) is an important secondary substance that plays a significant role in atmospheric chemistry and climate change. Although O<sub>3</sub> is essential in the stratosphere, it is harmful to human health in the troposphere, where this study was conducted. In recent years, O<sub>3</sub> pollution in the Beijing-Tianjin-Hebei (BTH), Yangtze River Delta (YRD), and Pearl River Delta (PRD) regions has deteriorated, which has become an important environmental problem. The generation of O<sub>3</sub> is closely related to meteorological factors. In this study, the weather classification method was adopted to study the effect of meteorological conditions on O<sub>3</sub> concentration. In the BTH region, Tianjin was selected as the representative city for the research. The real-time pollutants data, meteorological re-analysis data, and meteorological data in 2019 were combined for the analysis. The subjective weather classification method was adopted to investigate the effects of different weather types on O<sub>3</sub> concentration. The backward trajectory tracking model was used to explore the characteristics and changes of O<sub>3</sub> pollution under two extreme weather types. The results indicate there is a good correlation between O<sub>3</sub> concentration and ambient temperature. Under the control of low pressure on the ground and the influence of southwest airflow in the upper air for Tianjin, heavy O<sub>3</sub> pollution occurred frequently. The addition of external transport and local generation will cause high O<sub>3</sub> values when the weather system is weak. The O<sub>3</sub> concentration is closely related to ambient temperature. Continuous high-temperature weather is conducive to the photochemical reaction. The multi-day O<sub>3</sub> pollution process would occur when the weather system is robust. The first and second types of extreme weather are more likely to cause persistent O<sub>3</sub> pollution processes. Under the premise of stable emission sources, the change in weather patterns was the main reason affecting the O<sub>3</sub> concentration. This study aims to improve O<sub>3</sub> pollution control and air quality prediction in the BTH region and large cities in China. |
