摘要

摘要: 利用ROMS海洋数值模式对2006年冬季渤黄海的海洋动力环境进行模拟，基于温度、盐度模拟结果，使用谱混合模型进行水团分析，定义了渤海海峡地区的水交换区。并进一步讨论了冬季大风事件对水交换区的影响，给出了冬季大风影响下的渤黄海水交换特征。研究得出，冬季的黄海水团以“舌”形分布于渤海海峡地区，水交换区则表现为沿“舌”形边缘呈带状分布，具有西北——东南的走向趋势，并且在“舌”尖处的水交换面积最大。通过缩小研究范围，发现位于黄海最北部的沿岸海域并不参与渤黄海之间的水体交换。最后研究发现，冬季大风事件对渤海水交换具有促进作用，具体表现为：大风过程使黄海暖流对渤海的入侵更加深入，水交换区向渤海方向伸展，南部的水交换带变宽，河流径流进入渤海后与渤海水的混合区加大，并发生北移。

Abstract: The marine dynamic environment of the Bohai Sea and the Yellow Sea in the winter of 2006 is simulated by the Regional Ocean Modelling System (ROMS) marine numerical model. Using the simulated temperature and salinity, the water exchange zone between the Bohai Sea and Yellow Sea is defined through the Spectral Mixture Model (SMM). The influence of winter gales on the water exchange is also discussed. It is found that the Yellow Sea water masses in winter are distributed in a "tongue" shape in the Bohai Strait region, the water exchange zone presents a zonal distribution along the margin of the "tongue", with a tendency of running from northwest to southeast, and the water exchange is intensified at the tip of the "tongue". Besides, the coastal area in the northernmost Yellow Sea does not participate in the water exchange between the Bohai Sea and Yellow Sea. The result shows that the winter gale events play a role in enhancing the water exchange. It is specifically shown by the facts:the Yellow Sea warm current is enhanced to intrude the Bohai Sea by the gale process; the water exchange zone extends into the Bohai Sea; the water exchange belt in the southern part becomes wider; the mixture zone of river runoff with the Bohai Sea water upon its entry is enlarged and shifts northwards. Within two days after the gale process, the exchange zone retreats toward the Yellow Sea and the exchange zone resulted from the Huanghe River (Yellow River) runoff also shrinks back shoreward.
