  • 摘要: 为了对渤海海冰生消问题进行模拟,基于三维自由水面垂向分层动网格的Euler-Lagrangian模式,采用VC(Vertex-Centered)方式的非结构化有限体积方法离散三维浅水方程组,模拟渤海的水流运动过程。以此水动力场为背景,引入热力学过程的影响,对渤海海域的冬季结冰过程进行模拟,建立了海冰生消模型。其中热力学参数主要包括大气温度、相对湿度、风场特征、太阳辐射、感热通量系数以及潜热通量系数。以渤海2011/2012年常冰年的结冰过程为例,将各个热力学参数对冰情影响的敏感性进行分析,对模型进行了验证。结果表明,感热与潜热系数是对冰情影响最敏感的一项,即当感热和潜热通量系数仅减小了0.000 2后,其海冰的最大厚度就减小了15 cm。最后,通过连续实测的水动力数据与2009/2010年冬季的典型海冰灾害过程再一次对模型进行了验证,充分说明了模型具有较高的精确性、稳定性与实用性。
    Abstract: In order to preferably simulate the growth and decay of the ice in the Bohai Sea, based on three-dimensional (3-D) Euler-Lagrangian mode with free water surface vertically-stratified dynamic mesh, the 3-D shallow water equation set was discretized applying unstructured finite volume method with Vertex-Centered pattern. Further, the moving process of water current in the Bohai Sea was simulated. In the background of the above mentioned water dynamic field, the effect of detailed thermodynamic process was introduced, then the freezing process of the Bohai Sea in winter was stimulated, and finally the growth and decay model of ice in this sea area was established. The thermodynamic parameters mainly atmospheric temperature, relative humidity, wind field features, solar radiation, sensible heat flux, and latent heat flux coefficients were systematically investigated. Considering the ice-growth process in the Bohai Sea during 2011/2012-normal ice year as an example, the influence of each thermodynamic parameter on the ice condition and multiple parameters sensitivity were analyzed, and finally model was verified. The results showed that sensible heat and latent heat flux coefficients were the most sensitive parameters affecting the ice condition, i. e., the maximum thickness of sea ice decreased by 15 cm after sensible heat and latent heat flux coefficients were reduced only by 0.000 2. Finally, based on the continuously measured hydrodynamic data and the typical disaster process of sea ice happened during the winter of 2009/2010, the model was verified again, which completely illustrated the higher accuracy, stability, and practicality.
