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型解决不了的空间和时间尺度上。这将通过实地观测表面波特征和海气通量来实现。这些结果将能够更详细地描述由海洋表面波介导的大气和海洋之间的动力学联系。 该项目的教育部分将侧重于开发和实施新的教育模块，将表面波和海气相互作用纳入海洋工程和海洋学课程，并通过在新罕布什尔州拉伊海岸科学中心开发新的互动展览，与北方新英格兰的公众互动。海洋表面波影响气-海界面上的动量、热量和气体的平均通量。该项目将对厘米至十米波长的表面波进行全方位时空测量，测量这些波在多大程度上受到随时间变化的风力和长表面波的影响，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力对近岸沃茨年轻风浪增长和海气通量变化的影响程度。将量化陡表面重力波在调制湍流海气通量中的不稳定性的作用。研究结果将用于提高人们对在多变的环境条件下表面波对沿海地区海气相互作用影响的认识。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。

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.
