Abstract

To investigate the impact of sea-land breezes on PM_2.5 and O₃ pollution in coastal cities, the observation pollution and meteorological data of China National Environmental Monitoring Centre and ERA5 hourly data from 2016 to 2020 were analyzed to elucidate the influence of sea-land breezes circulation characteristics on PM_2.5 and O₃ levels in the coastal areas of Tianjin. The results showed there were 411sea-l and breezes days between 2016 and 2020, the sea-land breezes circulation frequently occurred from April to September, with the lowest frequency in December. The variation in seasonal characteristics of sea-land breezes circulation led to different impacts on PM_2.5 and O₃ levels. Land breeze circulation leads to PM_2.5 accumulation in coastal areas, and sea breeze circulation has a certain diffusion effect on PM_2.5 in winter. Sea-land breezes circulation change the distribution of O₃ in coastal areas, resulting in reduced valley values and increased daytime peaks of O₃ The peak concentration of O₃ in urban, suburban, and coastal locations were 4.1,8.9,16.0μg/m³ higher than the average peak value. The influence on peak value decreases as the distance from the coastline increases. A total of 94days of PM_2.5 and O₃ combined pollution from 2016 to 2020, and sea-land breezes occurred during 17 of these days. On PM_2.5 and O₃ combined pollution days with sea-land breezes, land breeze circulation transmitted PM_2.5 from the central urban area to the coast, while the sea breeze exhibited a scavenging effect on PM_2.5. The photochemical net decomposition rate of O₃ during land breeze circulation was higher than those days without sea-land breezes, while the photochemical net generation time of O₃ was longer during the sea breeze circulation. The effects of sea-land breezes circulation on O₃ and PM_2.5 reduced the frequency of PM_2.5 and O₃ composite pollution. Sea-land breezes' transport and redistribution of PM_2.5 and O₃ to coastal areas have a complex impact on regional pollution.
