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.

表面波调节大气和海洋之间的物理耦合。更好地理解这些小规模过程的物理学，对于改善近似值（或参数）的基础是将海洋和气候联系起来的天气和气候模型，尤其是随着地球气候的变化。该建议检查表面波方向和波浪破裂对波浪引起的运输的影响。这项研究的应用将是全球的，预计将改善对海洋与大气之间相互作用的理解和建模。本项目将提高对海面波和波浪破裂的几何形状，运动学，动力学，动态和统计的理解，并使用理论，数字，实验室和观测技术在空中互动中的作用及其在空中互动中的作用。非断裂和破坏波统计的高分辨率现场观察将用于计算波诱导的漂移，并提供该传输的参数，作为环境变量的函数。分析将量化与忽略或无法正确解决的有向波效应相关的错误，并将考虑波浪和波浪破坏上海中大规模运输的定向效应。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子和更广泛影响的评估来通过评估来支持的。
