低模内波能够在海洋盆地中传播，并调制距离其生成地点数千公里的海洋动力学。在这项研究中，远程生成的内波的影响，美国西海岸附近的内波能量学的影响进行了调查，现实迫使区域海洋模拟。在开放的边界，我们施加高频率的海洋状态变量从全球海洋模拟现实的大气和天文潮汐强迫。我们使用离散傅立叶变换（DFT）技术在分离进出的内潮能量通量在开放的边界，以量化内潮反射。虽然内潮反射随海绵粘度和/或海绵层宽度的增加而减少，但反射系数（λ）可高达73%。在远程内波的存在下，模型的方差和空间相关性变得更加符合系泊和测高数据集。结果证实，在开放边界处具有远程内波强迫的区域模型中可以实现改进的内波连续体。然而，应注意避免在这些边界处内波从内部过度反射。
Low mode internal waves are able to propagate across ocean basins and modulate ocean dynamics thousands of kilometers away from their generation sites. In this study, the impact of remotely generated internal waves on the internal wave energetics near the US West Coast is investigated with realistically forced regional ocean simulations. At the open boundaries, we impose high-frequency oceanic state variables obtained from a global ocean simulation with realistic atmospheric and astronomical tidal forcing. We use the Discrete Fourier Transform (DFT) technique in separating ingoing and outgoing internal tide energy fluxes at the open boundaries in order to quantify internal tide reflections. Although internal tide reflections are reduced with increasing sponge viscosity and/or sponge layer width, reflection coefficients (λ) can be as high as 73%. In the presence of remote internal waves, the model variance and spatial correlations become more in agreement with both mooring and altimetry datasets. The results confirm that an improved internal wave continuum can be achieved in regional models with remote internal wave forcing at the open boundaries. However, care should be taken to avoid excessive reflections of internal waves from the interior at these boundaries.
