The role of wave and wave breaking directionality in modulating the wave-induced drift at the ocean surface

表面波调节大气和海洋之间的物理耦合。更好地了解这些小尺度过程的物理性质，对于在联系海洋和大气的天气和气候模式中，特别是在地球气候变化的情况下，改进近似值（或参数化）至关重要。本文研究了表面波方向和波浪破碎对波浪引起的输运的影响。这项研究的应用将是全球性的，预计将导致对海洋和大气之间相互作用的理解和建模的改进。该项目将利用理论、数值、实验室和观测技术，促进对海洋表面波浪和波浪破碎的几何、运动学、动力学和统计学的理解，以及它们在海气相互作用中的作用。非破碎波和破碎波统计的高分辨率现场观测将用于计算波浪引起的漂移，并提供这种传输作为环境变量函数的参数化。分析将量化与忽略或不正确解决定向波效应有关的误差，并将考虑波浪和波浪破碎对上层海洋质量运输的定向效应。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

Surface waves modulate the physical coupling between the atmosphere and ocean. A better understanding of the physics of these small-scale processes is fundamental for improved approximations (or parametrizations) to be used in models of weather and climate that link ocean and atmosphere, particularly as Earth’s climate changes. This proposal examines the effects that surface-wave direction and wave breaking have on the transport caused by waves. The applications of this research will be global and are expected to lead to improvements in the understanding and modeling of the interaction between the ocean and the atmosphere.This project will advance understanding of the geometry, kinematics, dynamics and statistics of ocean surface waves and wave breaking and their role in air-sea interaction using theoretical, numerical, laboratory and observational techniques. High-resolution field observations of non-breaking and breaking wave statistics will be used to compute the wave-induced drift, and to provide parametrizations of this transport as a function of the environmental variables. Analyses will quantify the errors associated with ignoring, or not properly resolving, directional wave effects, and will consider the directional effects of waves and wave breaking on mass transport in the upper ocean.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
