This study presents findings from the FATIMA-YS campaign, an international collaborative effort to investigate marine atmospheric processes over the Yellow Sea, conducted at the Socheongcho Ocean Research Station (S-ORS) from June 20 to July 9, 2023. The Yellow Sea is a critical region for studying marine atmospheric boundary layer (MABL) dynamics due to its unique air-sea interaction processes driven by seasonal variability and complex coastal influences.

During the campaign, radiosonde observations at S-ORS captured the formation and evolution of a stable boundary layer (SBL) on June 30 and July 1, under conditions of warm air masses overlying cooler sea surfaces, accompanied by weak horizontal winds. These observations revealed a sharp temperature inversion near the surface, indicative of strong atmospheric stability and limited vertical mixing.

Turbulent fluxes were measured using eddy covariance instruments, capturing unique characteristics of air-sea interactions under stable conditions. These observational findings will be presented alongside numerical model simulations to explore the dynamics of the MABL under stable conditions.
