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

将对日益现实的制度中的涡流通量统计进行调查。拟议的工作将采用理想化的模拟，分析和理论发展，使用等密度海洋模式（HIM），以解决，特别是，适用性的位涡通量理论的基础上水平均匀（但垂直不均匀）准地转湍流更复杂的制度。这些研究将涉及以下几点：在理想化原始方程模式中获得收敛涡度统计所需的模式分辨率;绝热内部涡度通量与地面通量和地面强迫的相互作用;水平平均流不均匀性对涡度通量的影响;以及在地形存在下的涡动通量统计和动力学。通量理论成功地推广到现实制度将铺平道路这可能会导致业务气候模式的重大改进，从而提高对气候的海洋组成部分的理解。政府实验室资源可用于该项目，通过其模型的潜在改进使实验室受益，并使更大的科学界在海洋动力学方面进行不受阻碍的基础研究。

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.
