Abstract
This chapter describes the Japan/East Sea (JES) current systems. The chapter discusses the depiction of the seasonal variation of atmospheric forcing, numerical ocean model and integration, and simulated seasonal variability of temperature, salinity, and circulation. The JES circulation and thermohaline structure are simulated using Princeton Ocean Model (POM) with seasonal surface flux forcing. Two steps are used to initialize POM. During the first step POM is integrated for two years from zero velocity, and the January climatological temperature and salinity fields with climatological monthly mean surface wind stress. The final states of the restoring run are taken as initial conditions for the second step. During the simulation run, POM is integrated again for two more years with climatological monthly mean surface wind stress, net heat flux, and freshwater flux from the Comprehensive Ocean-Atmosphere Data Set (COADS) data. POM simulates the formation of the Japan/East Sea Sub-Polar Front (JES SPF) and its seasonal variation. The simulated thermal field shows a strong north-south thermal asymmetry across the SPF.
