Interaction of baroclinic eddy fluxes with inhomogeneous background flow, boundary layers and topography

将对日益现实的区域中的涡通量统计进行调查。拟议的工作将采用理想化的模拟、分析和理论发展，使用等周期海洋模式(HIM)，特别是解决基于水平均匀(但垂直非均匀)准地转湍流的位涡通量理论对更复杂区域的适用性。这些研究将涉及以下几点：在理想化原始方程模式中实现收敛的涡旋统计所需的模式分辨率；绝热内部涡通量与地面通量和地面强迫的相互作用；水平平均流不均匀对涡通量的影响；以及在地形存在的情况下的涡通量统计和动力学。通量理论的成功扩展到现实区域将为新的参数化方案铺平道路，该方案可能导致业务气候模式的重大改进，从而更好地理解气候的海洋成分。政府为该项目提供的实验室资源使该实验室受益于其模型的潜在改进，并使更大的科学界在产生不受阻碍的海洋动力学基础研究方面受益。

An investigation of eddy flux statistics in increasingly realistic regimes will be conducted. The proposed work will employ idealized simulation, analysis and theoretical development using an isopycnal ocean model (HIM) to address, in particular, the applicability of the potential vorticity flux theory based on horizontally homogeneous (but vertically inhomogeneous) quasi-geostrophic turbulence to more complex regimes. The studies will address the following points: the model resolution necessary to achieve converged eddy statistics in an idealized primitive equation model; interaction of adiabatic interior eddy fluxes with surface fluxes and surface forcing; the effects of horizontal mean flow inhomogeneities on eddy fluxes; and eddy flux statistics and dynamics in the presence of topography.The successful extension of the flux theory to realistic regimes will pave the way toward a new parameterization scheme that may lead to significant improvements in operational climate models, and hence to improved understanding of the ocean component of climate. The availability of government laboratory resources for this project benefits the laboratory via potential improvements in its models, and benefits the larger scientific community in generating unhampered fundamental research in ocean dynamics.
