Energy transfer mechanisms between the atmosphere and the deep ocean have been studied for many years. Their importance to the ocean’s energy balance and possible implications on mixing are widely accepted. The slab model by Pollard (Deep-Sea Res Oceanogr Abstr 17(4):795–812, 1970) is a well-established simulation of near-inertial motion and energy inferred through wind-ocean interaction. Such a model is set up with hourly wind forcing from the NCEP-CFSR reanalysis that allows computations up to high latitudes without loss of resonance. Augmenting the one-dimensional model with the horizontal divergence of the near-inertial current field leads to direct estimates of energy transfer spectra of internal wave radiation from the mixed layer base into the ocean interior. Calculations using this hybrid model are carried out for the North Atlantic during the years 1989 and 1996, which are associated with positive and negative North Atlantic Oscillation index, respectively. Results indicate a range of meridional regimes with distinct energy transfer ratios. These are interpreted in terms of the mixed layer depth, the buoyancy frequency at the mixed layer base, and the wind field structure. The average ratio of radiated energy fluxes from the mixed layer to near-inertial wind power for both years is approximately 12%. The dependence on the wind structure is supported by simulations of idealized wind stress fronts with variable width and translation speeds.

大气与深海之间的能量转移机制已经研究了很多年。它们对海洋能量平衡的重要性以及对混合的潜在影响已被广泛接受。Pollard的平板模型（Deep-Sea Res Oceanogr Abstr 17（4）：795–812，1970）是通过风-海洋相互作用推断出的近惯性运动和能量的公认模拟。通过NCEP-CFSR再分析的每小时强迫风建立了这样的模型，该模型允许进行高达高纬度的计算而不会损失共振。通过近惯性电流场的水平发散来增强一维模型，可以直接估算内部波辐射从混合层基础到海洋内部的能量转移谱。使用这种混合模型对1989年和1996年的北大西洋进行了计算，这分别与正和负北大西洋涛动指数有关。结果表明一系列具有不同能量传输比的子午状态。这些根据混合层深度，混合层底部的浮力频率和风场结构来解释。两年中，来自混合层的辐射能通量与近惯性风能的平均比率约为12％。对风结构的依赖得到了具有可变宽度和平移速度的理想化风应力锋面的模拟的支持。结果表明一系列具有不同能量传输比的子午状态。这些根据混合层深度，混合层底部的浮力频率和风场结构来解释。两年中，来自混合层的辐射能通量与近惯性风能的平均比率约为12％。对风结构的依赖性得到了具有可变宽度和平移速度的理想化风应力前沿的仿真的支持。结果表明一系列具有不同能量传输比的子午状态。这些根据混合层深度，混合层底部的浮力频率和风场结构来解释。两年中，来自混合层的辐射能通量与近惯性风能的平均比率约为12％。对风结构的依赖得到了具有可变宽度和平移速度的理想化风应力锋面的模拟的支持。
