CAREER: Investigating the impacts of sea breeze and steep surface gravity waves on nearshore air-sea fluxes

该项目的总体目标是促进对海洋表面波在调节地球大气和海洋之间的动量和热量交换中所起作用的理解，特别是在目前观测和区域模式无法解决的空间和时间尺度上。这将通过实地观测表面波特性和海气通量来实现。这些结果将使我们能够更详细地描述以海洋表面波为媒介的大气与海洋之间的动力联系。该项目的教育部分将侧重于开发和实施新的教育模块，将海洋工程和海洋学课程中的表面波和海气相互作用结合起来，并通过在新罕布什尔州莱伊海岸科学中心开发新的互动展览，与新英格兰北部的公众互动。本项目研究海洋表面波与海气通量之间的关系。海洋表面波影响着穿过海气界面的动量、热量和气体的平均通量。该项目将对波长为厘米至十米尺度的表面波进行全方位的时空测量，测量这些波被时变风强迫和长表面波改变的程度，以及这种改变对海气通量的影响。该项目将测量和评估时变风强迫对近岸水域年轻风浪生长和海气通量变化的影响程度。将量化陡地表重力波的间歇性在调制湍流海气通量中的作用。这些结果将用于提高对存在可变环境条件的沿海地区表面波对海气相互作用的影响的理解。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。

The overarching goal of this project is to advance understanding of the role that ocean surface waves play in mediating the exchange of momentum and heat between the earth’s atmosphere and ocean – especially over spatial and temporal scales that are presently under-resolved by observations and regional models. This will be achieved via a field campaign to make observations of surface wave characteristics and air-sea fluxes. The results will enable a more detailed description of the dynamical connection between atmosphere and ocean as mediated by ocean surface waves. The educational component of the project will focus on developing and implementing new educational modules that integrate surface waves and air-sea interaction within ocean engineering and oceanography curricula and engaging with the public of northern New England through the development of new interactive exhibits at the Seacoast Science Center of Rye, NH.This project addresses the relationship between ocean surface waves and air-sea fluxes. Ocean surface waves affect the mean fluxes of momentum, heat, and gas across the air-sea interface. The project will yield fully directional spatiotemporal measurements of surface waves with centimeter to decameter-scale wavelengths, the degree to which those waves are modified by time-varying wind forcing and long surface waves, and the effect of that modulation on air-sea fluxes. The project will measure and assess the degree to which time-varying wind forcing impacts the growth of young wind waves and variability of air-sea fluxes in nearshore waters. The role of intermittency in steep surface gravity waves in modulating turbulent air-sea fluxes will be quantified. The results will be used to improve understanding of the impact of surface waves on air-sea interaction in coastal zones in the presence of variable environmental conditions.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.
