Previous studies show that diurnal internal shelf waves (ISWs) are generated around the southern Ulleung Basin (UB) with their energy concentrated there. To investigate the spatio-temporal variation of diurnal ISWs, we use a high-resolution numerical ocean model that is forced by realistic 16 tidal constituents and involves a data assimilation scheme. The baroclinic total energy and the conversion rate of barotropic to baroclinic energy show higher values at the southern s...
