通过对南海东北部及台湾海峡邻近海域环流产生影响的各个动力因子进行量级分析，在Hurlburt等人数值模式的基础上，建立起分区性的正压、斜压耦合模式，以便能反映大陆架、大陆坡变化剧烈的底形效应对边缘海环流的影响。将该模式用于南海东北部及台湾海峡附近环流的数值研究。初步的试验计算结果表明，耦合模式能克服两层模式易发生“交面”和“交底”等现象的缺点，同时能反映斜压效应及底形效应的影响，使模拟的计算结果更切合实际，即：（1）黑潮通过巴士海峡侵入南海海域，并导致东沙群岛附近终年存在一个气旋涡；（2）台湾海峡西南海域的大陆架－大陆坡底形效应十分重要；（3）海水在台湾海峡的流动基本上为N向流动，流量约为2×10~6m~3·s-1；（4）模式中有类似于南海暖流的海流出现。
Based on Hurlburt et al. Numerical model, a series of positive pressure and baroclinic coupling models are established by carrying out the magnitude analysis of various dynamic factors that affect the circulation in the northeastern South China Sea and the Taiwan Strait so as to reflect the continental shelf, The effect of the steeply contoured continental slope on the marginal sea circulation. The model is applied to the numerical study of the circulation in the northeast of the South China Sea and the Taiwan Strait. The preliminary experimental results show that the coupling mode can overcome the shortcomings of the two modes, such as “Intersection ” and “Intersection ”. At the same time, it can reflect the influence of baroclinic effect and underfloor effect, The results are more realistic: (1) Kuroshio invaded into the South China Sea through the Bashi Channel and led to the existence of a cyclone vortex all year round in the Dongsha Islands; (2) the continental shelf-continental slope bottoming effect in the southwestern Taiwan Strait was very important; (3) ) The flow of seawater in the Taiwan Strait is basically N-direction with a flow rate of about 2 × 10 ~ 6m ~ 3 · s-1. (4) A current similar to the South China Sea warm current appears in the model.
