Focusing on predictability of the Kuroshio meandering, we have done an ensemble forecast experiment; the application of the method to the problem addressed seems to be the first comprehensive attempt in the community of physical oceanography. By a...

燧灘全域, 来島海峡および備讃瀬戸西部において, 2002年5月末から8月中旬まで4回にわたりCTD観測を実施した。観測データを2層1ボックスモデルで解析することにより, 燧灘成層域上下層の海水交換に対する移流と水平・鉛直混合の寄与を明らかにするとともに, 各層の熱収支を定量的に評価した。その結果, 海水交換に対しての寄与は上下層ともに鉛直混合よりも水平混合が数倍大きく, さらに, 下層では水平混合が移流よりも大きいことが判明した。また熱収支からは, 成層域下層の加熱に対する鉛直混合の寄与...

A two-way nested model has been constructed and applied to the idealized ocean where a uniform mean flow impinges on the isolated Gaussian-shaped seamount and produces two eddies (cold and warm) in the depths. The performance of the nested model h...

On the basis of the Princeton Ocean Model, a robust diagnostic model is developed to calculate the residual currents in the Hiuchi-Nada, a semi-enclosed bay of the Seto Inland Sea. The input water temperature and salinity data are from six hydrogr...

A high-resolution ocean general circulation model is developed to simulate connections between the Kuroshio path variations and mesoscale eddy activities as realistically as possible. The climatological mean of the modeled Kuroshio takes a nearsho...

A triply nested ocean general circulation model was used to examine how the model horizontal resolution influences the Kuroshio in the East China Sea (ECS) and the sea level variability. As the model resolution increases from 1/2° to 1/18° the pat...

黒潮の沿岸よりの流れが紀伊半島に当たることで発生する振り分け潮について,水平解像度1/18度の高解像海洋循環モデルを使って研究した。1997年のモデル再現実験データを観測結果と比較して,以下の結果を得た。紀南海域の平均的な水位分布は,振り分け潮による沿岸の低気圧性渦に伴うものであるが,モデルの年平均値は,この水位の平均描像を再現できない。しかし,個々のイベントについては平均描像と酷似した水位分布を再現できる。これは,モデルでは振り分け潮の発生頻度は10%ほどであるが,観測では70%の高頻度...

Current measurements and conductivity-temperature-depth surveys of the lagoon and ocean at Majuro Atoll, the Republic of the Marshall Islands, were made from January 10 to 24, 1997. A vertically integrated tidal current model reproduced qualitativ...

A three-dimensional tidal current model is developed and applied to the East China Sea (ECS), the Yellow Sea and the Bohai Sea. The model well reproduces the major four tides, namely M 2 , S 2 , K 1 and O 1 tides, and their currents. The horizon...

Observed zooplankton data show that the number of outer bay species of zooplankton appearing in the central part of Tokyo Bay have increased in recent years. Because these zooplankton cannot reproduce in the inner bay, they must be brought into th...
