项目摘要
0425305/0425395Intellectual MeritThis project will produce an important advancement in knowledge and understanding within the air-sea interaction community and more broadly in the area of air-water fluxes. Modern instrumental techniques such as infrared imaging, digital particle image velocimetry, laser-induced fluorescence, bulk gas flux, and air-side heat and momentum flux measurement methods will be combined to perform a detailed study of the hydrodynamics of air-water heat fluxes in a specially constructed controlled-turbulence wind flume tank at the University of Washington. The objectives of the proposed research are to:1. Conduct a detailed, controlled study of the hydrodynamics governing air-water heat and gas fluxes and to evaluate the effectiveness of active and passive infrared techniques to infer heat and gas transfer velocities.2. Determine if heat can be used as a proxy tracer for air-water gas transfer.3. Determine if surface penetration theory provides a more accurate conceptual model of air-water heat and gas transfer than surface renewal theory.Broader ImpactsThe proposed activity will benefit society by contributing to our understanding of the natural environment. This improved understanding will lead to better parameterizations of air-sea fluxes relevant to global climate change and numerical weather forecast modeling. The importance of air-sea fluxes to the Earth's climate is well documented. Heat, in the form of latent heat released by condensing water vapor, provides much of the energy driving global atmospheric circulation. Gas transfer plays an integral role in biogeochemical cycling and is of interest because of societal concerns about the effect of greenhouse gases and anthropogenically induced global climate change.The project will also promote teaching, training, and learning through participation of a graduate student (recruited minority, see below), sending the graduate student to scientific meetings to present results, and mentoring a current junior staff member during her undergraduate studies. The activity will broaden the participation of underrepresented groups by recruiting a minority graduate student (using resources such as the ASLO Minorities in Aquatic Sciences Program), employing a part-time female technician who is also a full-time student in the oceanography program at the University of Washington, and by the PI annually teaching in a middle school program at Seattle Girls School with a high percentage of minority students. The activity will enhance infrastructure for research and education by building a unique facility for studying air-sea interaction that will be made available for use by others. The activity will have broad dissemination of results to enhance scientific and technological understanding thorough participation in the annual College of Engineering Open House, establishment of a web site devoted to dissemination of data and results from the project, and publications in peer reviewed journals..
0425305/0425395智力价值该项目将在海气相互作用领域以及更广泛的气水通量领域的知识和理解方面取得重要进展。现代仪器技术,如红外成像,数字粒子图像测速仪,激光诱导荧光,散装气体通量,空气侧的热量和动量通量测量方法将结合起来,在华盛顿大学的一个专门建造的控制湍流风水槽罐进行空气-水热通量的流体动力学的详细研究。本研究的主要目的是:1.对控制空气-水热量和气体通量的流体动力学进行详细的受控研究,并评估主动和被动红外技术推断热量和气体传递速度的有效性。确定热是否可以用作空气-水气体传输的代理示踪剂。确定表面渗透理论是否比表面更新理论提供了更准确的空气-水热量和气体传递的概念模型。更广泛的影响拟议的活动将通过促进我们对自然环境的理解而造福社会。这种更好的理解将导致更好的参数化的海气通量有关的全球气候变化和数值天气预报建模。海气通量对地球气候的重要性已有充分的文献记载。热量以凝结的水蒸气释放的潜热的形式提供了驱动全球大气环流的大部分能量。气体迁移在地球化学循环中起着不可或缺的作用,由于社会对温室气体影响和温室效应引起的全球气候变化的关注,该项目也将通过研究生的参与促进教学,培训和学习(招募的少数民族,见下文),送研究生到科学会议上展示结果,并在本科学习期间指导一名现任初级工作人员。这项活动将扩大代表性不足的群体的参与,办法是招募一名少数民族研究生(利用ASLO少数民族水产科学方案等资源),雇用一名兼职女技术员,她也是华盛顿大学海洋学方案的全日制学生,并由PI每年在少数民族学生比例较高的西雅图女子学校的中学方案中任教。这项活动将加强研究和教育的基础设施,建立一个独特的设施,用于研究海气相互作用,供其他方面使用。这项活动将广泛传播成果,通过参加每年的工程学院开放日,建立一个专门传播项目数据和成果的网站,并在同行评审的期刊上发表文章,提高对科学和技术的认识。
