| 摘 要： | 将Casulli差分格式引入三维物理海洋模型计算，模拟了北部湾风生流及密度流。模拟结果表明，夏季西南季风在北部湾导致一个顺时针环流，夏季海水密度梯度导致一个逆时针方向的环流，密度流明显强于风生流；冬季东北寒潮导致一个逆时针环流。模拟结果不支持北部湾夏季为一顺时针环流、冬季为逆时针环流的传统结论，而支持终年为逆时针环流的观点。

| Abstract: | The Casulli's difference scheme was introduced into the three dimensional ocean model in the present paper, and the wind-driven current and thermohaline current were simulated. The results show that, southwesterly monsoon in summer induces a clockwise circulation in the Beibu Gulf, and the density gradient induces an anti-clockwise one, but the density currents are more intense than the wind-driven one in summer, especially in surface layer, in addition, the northeasterly monsoon in winter induces an anti-clockwise circulation. The simulated results don't support the traditional conclusion that there is a clockwise circulation in Beibu Gulf in summer and a counter-clockwise one in winter, instead of supporting the statement that a counter-clockwise circulation exists in the Beibu Gulf all year round. |
