Abstract
The circulation and characteristic oceanic phenomena in the Sea of Okhotsk have been clarified for the past 20 years. These phenomena serve as good subjects of Geophysical Fluid Dynamics, which is applied to the following phenomena. 1. Offshore branch of the East Sakhalin Current interpreted as a western boundary current and the Sverdrup balance, 2. Coastal branch of the East Sakhalin Current interpreted as Arrested Topographic Waves by the alongshore wind stress, 3. Tidal currents amplified by diurnal Topographic Rossby Waves, 4. Rossby Normal Modes in the Kuril Basin, 5. Barotropic instability of the Soya Warm Current, 6. Baroclinic instability associated with strong mixing near the Kuril Straits, 7. Dynamical interaction between sea ice and coastal ocean.
