In numerical ocean models, the effect of waves on currents is usually expressed by either vortex-force or radiation stress representations. In this paper, the differences and similarities between those two representations are investigated in detail in conditions of both conservative and nonconservative waves. In addition, comparisons between different sets of equations of mean motion that apply different representations of wave-induced forcing terms are included. The comparisons are useful for selecting a suitable numerical ocean model to simulate the mean current in conditions of waves combined with currents.

三维辐射应力与涡力表示之间的关系

在数值海洋模型中，波浪对洋流的影响通常由涡旋力或辐射应力表示。在本文中，在保守和非保守波的条件下详细研究了这两种表示之间的差异和相似之处。此外，还包括应用不同表示的波浪诱导强迫项的不同组平均运动方程之间的比较。这些比较有助于选择合适的数值海洋模型来模拟波浪与洋流结合的条件下的平均洋流。
