． 海洋环流强烈影响着内潮的辐射和破碎，刺激了内潮混合的空间不均匀性和时间变化。内部潮汐与环流相互作用的定性和定量表征对多尺度环流动力学至关重要。在区域环流模拟取得重大进展的基础上，通过确定性解析吕宋海峡内潮能辐射路径的动力学，获得了观测支持的吕宋海峡内潮能场。当已知吕宋海峡最强大的内部潮汐与黑潮相互作用时，这些路径就形成了。研究发现，吕宋海峡内的辐射潮型、局部耗散效率和能量场对跳跃、循环和泄漏黑潮路径有不同的响应。我们对动力学的新见解和我们对环流中控制折射机制的澄清，创造了在气候模式中更好地代表内部潮汐的潜力。
. Abstract Ocean circulation strongly influences how internal tides radiate and break and stimulates the spatial inhomogeneity and temporal variation of internal tidal mixing. Qualitative and quantitative characterizations of interactions between internal tides and general circulation are critical to multi-scale circulation dynamics. Based on significant progress in regional circulation simulation, we obtain an observation-supported internal tide energy field around Luzon Strait by deterministically resolving the dynamics of the radiating paths of the internal tide energy. These paths are created when the known most powerful internal tide of Luzon Strait interacts with the Kuroshio Current. We found that the radiating tidal pattern, local dissipation efficiency, and energy field respond differently to the leaping, looping, and leaking Kuroshio paths within Luzon Strait. Our new insights into the dynamics and our clarifying the controlling refraction mechanism within the general circulation create the potential for internal tides to be represented better in climate models.
