摘　　要：利用2023年夏季在乐亭县开展的观测实验数据和相关气象数据及环境数据,分析渤海湾地区海陆风环流及其对臭氧污染的影响。结果表明,海陆风环流可以影响臭氧在海陆间输送,可能导致渤海湾上空及沿海地区臭氧污染。HYSPLIT后向轨迹模拟解析共有5条主要气团轨迹影响到实验观测地区,其中有2条偏南方向气团通过短距离输送进入实验地区,对该区域的臭氧污染贡献率高达65%。Based on the data from the observation experiment carried out in Laoting County in the summer of 2023,and the related meteorological and environmental data,the sea-land breeze circulation over Bohai Bay area and its influence on ozone pollution were analyzed.The results showed that the sea-land breeze circulation could affect the transport of ozone between sea and land,which might lead to ozone pollution over Bohai Bay and coastal areas.HYSPLIT backward trajectory simulation indicated a total of five major air mass trajectories affecting the experimental observation area,among which two southerly air masses were transported into the experimental area through a short-distance transportation,contributing up to 65%of ozone pollution in the area.
