| Abstract: | オホーツク海の海洋循環や特徴的な海洋現象が，この20年程で一挙に明らかになってきた．これらの現象は地球流体力学のよい題材となるものが多く，本稿では地球流体力学を用いることで明快に解釈できる以下の現象に関して概説する．1．西岸境界流と解釈される東樺太海流の沖合分枝とスベルドラップバランス, 2. 岸沿い方向の風応力で駆動される沿岸捕捉流と解釈される東樺太海流の沿岸分枝, 3.日周潮地形性ロスビー波の励起によって増幅される潮流, 4.千島海盆に生ずるロスビー波による固有振動, 5. 宗谷暖流の順圧不安定, 6. 千島海峡周辺での強い混合に伴う傾圧不安定, 7. 海氷と沿岸海洋の力学的相互作用． | | 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. |
