我们描述了一个新的框架来表示波对电流的影响,包括几个近似值(斯托克斯漂移,伯努利头,准静压)和参数化的垂直混合由于波破碎。该框架改进了现有的方法,不受水深或单色假设的限制。近似验证光谱和电流配置从一个模型配置在南加州。斯托克斯漂移近似使用两个尺度来解释宽带谱,包括混合风-海和涌浪。斯托克斯漂移迭代估计,表面漂移速度和斯托克斯输运的约束,更有效,同时给出更小的误差相比,频谱重建方法。在270米水平网格分辨率下,一个月的海洋静力模式的解决方案表明,波浪对平均环流和近地面的中尺度流变率的影响相对较小。当湍流朗缪尔数较小时,波浪使近地面涡度和散度方差增大。
We describe a new framework to represent wave effects on currents, including several approximations (Stokes drift, Bernoulli head, and quasi-static pressure) and a parameterization of the vertical mixing due to wave breaking. The framework improves over existing methods not limited by water depth or monochromatic assumptions. The approximations are validated with spectra and current profiles from a model configuration in Southern California. The Stokes drift approximation uses two scales accounting for broadband spectra, including mixed wind-sea and swell. The Stokes drift is estimated iteratively, constrained by the surface drift velocity and Stokes transport, being more efficient while giving smaller errors compared to a spectrum reconstruction approach. One-month-long hydrostatic ocean model solutions at 270 m horizontal grid resolution show that waves have relatively small impacts on the mean circulation and mesoscale current variability near the surface. Waves increase the vorticity and divergence variance near the surface when the turbulent Langmuir number is small.
