来自破碎的海洋内波的湍流混合驱动了海洋中水、热量和其他重要气候示踪剂的垂直输送，从而在形成气候系统内热量和碳的循环和分布方面发挥了重要作用。然而，将内波驱动的混合与其对气候的影响联系起来是一项艰巨的挑战，因为它需要了解内波的复杂生命周期——包括产生、传播和进入湍流——以及这些过程在多样化、快速演变的海洋环境中的时空变异性。在这篇综述中，我们追溯了从潮汐、风和地转流到内波混合的能量路径，并将这种混合与全球气候系统联系起来。此外，我们讨论了未来工作的途径，包括理解内波场内的能量传递过程，内波如何被背景电流修改，以及内波混合如何在全球气候系统中得到整合。
Turbulent mixing from breaking oceanic internal waves drives a vertical transport of water, heat and other climatically important tracers in the ocean, thereby playing an important role in shaping the circulation and distributions of heat and carbon within the climate system. However, linking internal wave-driven mixing to its impacts on climate poses a formidable challenge, since it requires understanding of the complex life cycle of internal waves — including generation, propagation and breaking into turbulence — and knowledge of the spatio-temporal variability of these processes in the diverse, rapidly evolving oceanic environment. In this Review, we trace the energy pathways from tides, winds and geostrophic currents to internal wave mixing, connecting this mixing with the global climate system. Additionally, we discuss avenues for future work, including understanding energy transfer processes within the internal wave field, how internal waves can be modified by background currents and how internal wave mixing is integrated within the global climate system.
