地球上的沃茨聚集在浅的、不规则的、相互连接的盆地中。在太阳的加热和风的推动下，海洋无休止地循环。海洋环流是这种流动在盆地尺度上的持续模式。它是物理海洋学的心脏和灵魂，从流体动力学原理解释和预测流动是物理海洋学家的主要目标。沿着运动模式，相关的压力场、温度场、盐度场和密度场也是完整的海洋环流理论的必要组成部分，因为它们与海洋的运动有着动力学上的联系。海洋环流引起的物理问题在实验上和理论上都是一个难题。从理论流体力学的观点来看，困难主要来自循环的再循环特性。流体聚集到一个单一的、高度扭曲的盆地中。
The waters of the earth are gathered in shallow, irregular, interconnecting basins. Heated by the sun and driven by the wind, the oceans circulate endlessly. The general circulation of the ocean is the persistent pattern of this flow on the scale of the basins. It is the heart and soul of physical oceanography, and the explanation and prediction of the flow from the principles of fluid dynamics is the chief goal of the physical oceanographer. Along with the pattern of the motion, the associated fields of pressure, temperature, salinity, and density are also necessary components of a complete theory for the ocean circulation since they are dynamically linked to the motion of the oceans. The physical problem posed by the general circulation of the oceans is a difficult one both experimentally and theoretically. From the point of view of theoretical fluid mechanics the difficulty springs fundamentally from the recirculating character of the circulation. The fluid is gathered into a single, though highly contorted basin.
