| 摘 要： | 提出了一种模拟三维海流运动的隐式差分方法，井给出其计算步骤。通过对该差分方法的稳定性分析可以发现，它的时间步长取值有较大的灵活性。该方法被用于崖门海域的海流模拟。实例计算表明，该差分方法计算过程稳定，计算结果合理，能较好地反映出三维海流运动的特征。

| Abstract: | An implicit difference scheme of simulating three-dimensional oceancurrent is developed and its calculating method is proposed. It is known that a bigtime-step can be used in this method by analyzing the stability of the differencescheme. The model is used in the simulation of ocean current in the Yamen waterarea. The real case shows that the difference scheme is stable and the simulatingresults are rational. The three-dimensional model can describe better the structuralcharacteristics of ocean current. |
