| Abstract: |
| The Bohai Sea is a shallow semi-enclosed inner sea with an average depth of 18 m and is located at the west of the northern Yellow Sea. The climatological circulation pattern in summer of the Bohai Sea is studied by using a wave-tide-circulation coupled model. The simulated temperature and the circulation agree with the observation well. The result shows that the circulation pattern of the Bohai Sea is jointly influenced by the tidal residual current, wind and baroclinic current. There exists an obvious density current along the temperature front from the west part of the Liaodong Bay to the offshore area of the Huanghe Estuary. In the Liaodong Bay there exists a clockwise gyre in the area north to the 40°N. While in the area south to the 40°N the circulation shows a two-gyre structure, the flow from the offshore area of the Huanghe Estuary to the Liaodong Bay splits into two branches in the area between 39°N and 40°N. The west branch turns into north-west and forms an anti-clockwise gyre with the south-westward density current off the west of the Liaodong Bay. The east branch turns to the east and forms a clockwise gyre with the flow along the east coast of the Liaodong Bay. The forming mechanism of the circulation is also discussed in this paper. |

渤海是一个平均深度18m浅的半封闭海。本文利用波浪-潮汐-环流耦合模式研究了渤海夏季的气候环流模式。模拟温度和环流与观测吻合较好。结果表明，渤海环流受潮汐余流、风、斜压海流共同作用。
辽东湾西部至黄河外海的温度锋面区域有明显的密度流。在辽东湾，40°N以北地区存在一个顺时针环流；40°N以南地区存在一个双涡旋结构。从域黄河入海口外海到的辽东湾流在的39~40°N之间的区域分裂成两个分支，西支变成西北和在西南方的电流密度下西辽东湾形成一个逆时针环流之间的流动；东支转向东，沿辽东湾东海岸形成一个顺时针流动。文中还讨论了环流的形成机制。 |
