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

该项目的首要目标是增进对海洋表面波在调节地球大气层和海洋之间的动量和热量交换方面的作用的了解，特别是在空间和时间尺度上，目前观测和区域模型未能解决这些问题。这将通过实地观测表面波特征和海气通量来实现。这一结果将使我们能够更详细地描述海洋表面波所介导的大气和海洋之间的动力联系。海面波影响着海气界面上的动量、热量和气体的平均通量。该项目将产生厘米到分米尺度波长的表面波的全定向时空测量，这些波被时变风强迫和长表面波修改的程度，以及这种调制对海-气通量的影响。该项目将测量和评估随时间变化的风强迫对近岸水域年轻风浪的增长和海气通量变化的影响程度。陡峭的表面重力波的间歇性在调节海-气湍流通量中的作用将被量化。这一结果将被用来更好地理解在环境条件变化的情况下，表面波对海岸带海气相互作用的影响。这一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智力优势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.
