摘要:
以红海湾夏季和冬季的水文观测为基础，分析红海湾的海流特征，并将其作为数学模型的验证资料。建立基于三角形网格的二维海流数学模型，采用南海区域环流预测结果作为边界条件，对红海湾进行了海流数值模拟，并对模型进行验证。研究结果表明，模型计算结果与实测结果一致，夏季和冬季海流季节性差异较大，此区域主要受季风影响，存在较明显的季风环流，与南海海流的基本特征一致。在以上水动力模型的基础上建立温排水数学模型，进行夏季和冬季的温排水预测，分析其对海域产生的环境影响。
Based on the hydrological observations of the Red Bay in summer and winter, the characteristics of the Red Bay current were analysed and used as a verifying data of the mathematical model. A mathematical model of two-dimensional ocean current based on triangular mesh is established. The model uses the prediction result of the South China Sea regional circulation as the boundary condition, and the numerical simulation and verification of the sea current are carried out in the Red Bay. The results show that the calculated results of the model agree with the measured data. The seasonality of the current is quite different in summer and winter. This area is mainly affected by monsoon, and there is a distinct monsoon circulation, which is consistent with the basic characteristics of the South China Sea current. Based on the above hydrodynamic model, a mathematical model of thermal drainage is established, and the thermal drainage in summer and winter is predicted, and the environmental impact on the sea area is analysed.
