To understand the formation area of High-Salinity Intermediate Water (Smax-IW) with a density of more than 27.3 σθ in the Japan Sea and its transport path, historical hydrographic data from winter to spring and Conductivity-Temperature-Depth (CTD) data by the Japan Meteorological Agency in 2009 are examined. Spatial distributions of salinity and acceleration potential on the 27.33 σθ surface suggest that Smax-IW flows southwestward from the subarctic area north of the polar front, where Smax-IW outcrops and has an opportunity to become denser by direct winter cooling.
