Large-scale land-sea interactions extend ozone pollution duration in coastal cities along northern China.

ABSTRACT: Land-sea atmosphere interaction (LSAI) is one of the important processes affecting ozone (O₃) pollution in coastal areas. The effects of small-scale LSAIs like sea-land breezes have been widely studied. However, it is not fully clear how and to what extent the large-scale LSAIs affect O₃ pollution. Here we explored an O₃ episode to illuminate the role of large-scale LSAIs in O₃ pollution over the Bohai-Yellow Seas and adjacent areas through observations and model simulations. The results show that the northern Bohai Sea's coastal region, influenced by the Mongolian High, initially experienced a typical unimodal diurnal O₃ variation for three days, when O₃ precursors from Beijing-Tianjin-Hebei, Shandong, and Northeast China w
