Times Cited Count：6 Percentile：16.73(Oceanography)This study aims at reproducing branches of the Tsushima Warm Current making use of an ocean general circulation model, which is important for movement of pollutants in the Japan Sea. The model was laterally exerted by volume transports measured by ADCP through the Tsushima Straits and the Tsugaru Strait. Sea level variation measured by coastal tide-stations as well as satellite altimeters is assimilated into the numerical model. It was demonstrated that an assimilation of sea level variation at the coastal tide-stations is useful to simulate oceanic condition in the nearshore region.

An assessment system for oceanic environment in the Japan Sea has been developed at Japan Atomic Energy Agency. Realistic reproduction of oceanic condition such as current and temperature is necessary to calculate movement of materials in the ocean. A circulation in the Japan Sea is strongly effected by the Tsushima Warm Current through the Tsushima Straits and the Tsugaru Warm Current through the Tsugaru Strait. In this study, an ocean general circulation model was drived by realistic volume transports of the Tsushima Warm Current and the Tsugaru Warm Current observed by Kyushu University and JAEA, respectively. In addition, the satellite altimeter data and sea surface height at coastal stations were assimilated by the Kalman filter. Model results well reproduced current field along the Japanese coast observed from September to October in 2000.
