本文建立了黄海热结构的一维三层模式.模式中包含海面热输入和风混合作用下形成的上均匀层,由潮流混合作用形成的下均匀层以及具有一定厚度的温跃层.我们分别得到了上、下层的卷挟速度.本模式较好地描述了黄海季节温跃层的成长和消衰过程,并比较成功地模拟出了黄海冷水团、苏北沿岸锋及其表层冷水等重要水文现象,对它们的形成机制和青岛外海水域的强温跃层现象作了较合理的解释,认为潮流混合对苏北沿岸锋及青岛外海水域强温跃层的形成起了关键性的作用.在风混合和潮混合作用下,一部分高营养盐的下层水被卷挟到上层,这对提高海区的生物生产力具有重要意义.
In this paper, a one-dimensional three-layer model of the Yellow Sea thermal structure is established, which includes an upper uniform layer under the sea surface heat input and wind mixing, a lower uniform layer formed by tidal current mixing and a thermocline layer with a certain thickness. The upper and lower strapping speed.The model better describes the growth and decline of the thermocline in the Yellow Sea and successfully simulates the important hydrology such as the Yellow Sea cold water mass, the northern coastal front and its surface cold water Phenomenon, the formation mechanism of them and the phenomenon of strong thermocline in the offshore waters of Qingdao have been explained reasonably, and the trend of mixing has played a key role in the formation of the strong thermocline in the coastal areas of North Jiangsu and the offshore waters of Qingdao. Under the mixed action of wind and tide, a part of high nutrient salt water is entrained in the upper layer, which is of great significance to improve the biological productivity in the sea area.
