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.

表面波调制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特性，对于改进用于连接海洋和大气的天气和气候模型的近似值（或参数化）至关重要，特别是在地球气候变化的情况下。本提案研究了表面波方向和波浪破碎对波浪引起的输运的影响。这一研究的应用将是全球性的，预计将导致改进对海洋与大气之间相互作用的理解和建模，这一项目将利用理论、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学、运动学、动力学和统计学及其在海气相互作用中的作用的理解。非破碎波和破碎波统计数据的高分辨率实地观测将用于计算波浪引起的漂移，并作为环境变量的函数提供这种运输的参数化。分析将量化与忽略或未正确解决定向波浪效应相关的错误，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NSF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。
