本文对位于日本最大岛屿本州东北海岸的大槌湾进行了数值模拟，利用海洋环流模式（OGCM）和巢格系统来说明海湾环流的季节变化。一年中，一个逆时针的环流在海湾中占主导地位，正如观测研究所暗示的那样，尽管它在海湾的海湾口部分在冬季有所改变。此外，春秋季受河水流量的影响，表层有较强的流出。太平洋海水进入海湾受平均环流的影响，但也受春季至秋季斜压潮汐的影响。受斜压潮汐影响的太平洋海水入侵可能对大槌湾的环境产生影响。
A numerical simulation of Otsuchi Bay located on the northeast coast of the Honshu, the largest island of Japan, is conducted, using an ocean general circulation model (OGCM) with a nested-grid system in order to illustrate seasonal variability of the circulation in the bay. Through a year, an anticlockwise circulation is dominant in the bay, as observational studies have implied, although it is modified in the bay-mouth-half of the bay in winter. In addition, there is an intense outflow at the surface layer during spring to autumn, influenced by river water discharge. Intrusion of the Pacific water into the bay is influened by mean circulations, but it is also influenced by baroclinic tides from spring to autumn. Pacific water intrusions affected by baroclinic tides may have an impact on the environment in Otsuchi Bay.
