渤海冬夏季环流的数值研究

用三维陆架海模式对渤海的冬夏季环流进行了研究。指出：就垂向平均而言、渤海的冬夏季环流结构基本一致，且与垂向平均的潮余流相似。渤海环流有显著的三维结构，冬季，上层主要为风漂流，下层主要为风漂流，下层为补偿流；夏季；潮，风和密度对环流的贡献较大，表现为复杂的三维结构。

Numerical Study of the Winter and Summer Circulation in the Bohai Sea

The winter and summer circulation in the Bohai Sea are investigated with a three dimensional shelf sea circulation model (HAMSOM).The results show that the vertically averaged circulation in both winter and summer almost have the same pattern that is similar to the vertically averaged tidal residual circulation.The tidal residual circulation as well as the winter and summer circulation has significant three dimensional structure:there are wind draft in the upper layers and compensating current in the lower layers during the winter time.In summer,all of the tide,wind and thermhaline contribute to the general circulation which present complex three dimensional structure.The three dimensional structure of the circulation has been discussed in detail.
