Abstract：The sea fog over Bohai Sea from April 28 to 29 2015 is analyzed with FY satellite data, MTSAT satellite data, ERA Interim reanalyzed data, buoy stations data and automatic weather stations data, with the air-sea interaction during the formation and development of the sea fog analyzed intensively. A lower atmosphere inversion layer rose and a wet area of greater than 90％ expanded upward and westward, beneficial to the formation of Bohai Sea fog. There was evident east and southeast wind during the sea fog event, in favor of vapor transporting from the Yellow Sea to the Bohai Sea. Strong vapor flux moved from the Bohai Straits to the Bohai Sea, enhanced vapor transport upon it and provided necessary vapor for the formation of sea fog. Bohai Sea air temperature was greater than sea surface temperature, sea surface net turbulence heat exchange caused by wind shear delivered heat from the atmosphere to the sea, then warm moist air cooled down and saturated and advection cooling fog generated.
