Characteristics analysis of sea-land breeze circulation and ozone in Bohai Bay
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.
