The role of wind on the detachment of low salinity water in the Changjiang Estuary in summer

摘要：

　　Two detachment processes of low salinity water (LSW) in the Changjiang Estuary in July 2006,and the role of wind on detaching the LSW in particular,are explored with a three-dimensional numerical model.Results show that wind is the most important dynamic factor in the two detachment processes of the LSW.Wind mixing,wind-driven northward current and wind-induced upwelling are three driving forces on detaching the LSW,which increase the salinity in the upper layer in the detachment region along the 30 m isobaths and separate the offshore LSW from the near-shore main body of LSW.The diagnostic analysis further indicates that the increase of salinity in the detachment region is mainly due to northward current which transports high salinity water from the south.
