首先从海洋原始方程组出发，讨论了刚盖模式（RL）与自由表面模式（FF）的闭合方程组的异同；在包括海底地形的同一模式海盆中，在相同外力──定常的海面风应力和加热场──强迫下，使用这两种模式分别进行了大洋环流的数值模拟。由于选用了适当的初值、运用了时间步长调整技术等，从而加快了模拟速度，节省了CPU时间。对此两模式的结果本文进行了详细比较，尤以流函数、水位、上层温度及垂直速度作为讨论的重点。比较结果证实：使用这两个模式模拟出的大洋环流的各种物理量是一致的。另外，又从大洋环流形成机制上对此一致性作了进一步讨论。最后对这两种模式进行了评价。
First of all, starting with the marine primitive equations, the similarities and differences of the closed equations between the rigid-cover model (RL) and the free-surface model (FF) are discussed. In the same model basin including the seafloor topography, And the heating field ─ ─ forced, using these two models were carried out numerical simulation of ocean circulation. Due to the selection of the appropriate initial value, the use of time-step adjustment technology, which speeds up the simulation speed, saving CPU time. The results of the two modes are compared in detail in this article, especially the stream function, water level, upper temperature and vertical speed as the focus of the discussion. The comparison results confirm that the physical quantities of the ocean circulation simulated using these two models are consistent. In addition, this consistency is further discussed from the mechanism of oceanic circulation. Finally, the two models were evaluated.
