【摘要Abstract】：密度补偿是物理海洋学的经典问题。我们利用密度-涩度(s-p)坐标，对密度补偿率进行精准量化，并提出了一种描述密度补偿的新方法。对于混合层以下的海洋，由于大尺度流动通常沿等密面运动，等密面上位密保持不变，位涩是唯一变化的变量，使得水平密度补偿率的物理意义变得不清晰。在本讲座中，还将探讨海洋中的侧向混合能量学问题。类似于经典的有效势能（APE）概念，海洋中的侧向混合的能量可以从水平混合有效势能（HMAPE）、等密混合有效势能（IMAPE）以及混合增密有效势能（CAPE）等不同角度进行探索研究。为了有效释放CAPE，需要对混合张量进行旋转，并且混合系数呈现各向异性特征。侧向混合是海洋环流理论中尚待深入探索的重要领域之一，其机物理制及参数化是当前的重大科学挑战。
Density compensation is a classic topic. Using the density-spicity (s-p) coordinate, we can accurately quantify the density compensation rate, and a new way of describing the density compensation is proposed. The meaning of horizontal density compensation rate for the ocean below the mixed layer is unclear because large-scale flows tend to follow isopycnal surfaces; on isopycnal surfaces, potential density is constant, so that the only variable is potential spicity. The energetics of lateral mixing in the ocean are examined. Parallel to the classic APE (Available Potential Energy), lateral mixing in the ocean can be examined in terms of HMAPE (Horizontal Mixing Available Potential Energy), IMAPE (Isopycnal Mixing Available Potential Energy), and CAPE (Cabbeling Available Potential Energy). To effectively release CAPE, the mixing tensor must be rotated, and the mixing coefficient is anisotropic. Lateral mixing is one of the last virgin lands in the theory of ocean circulation, the mechanism and parameterization of lateral mixing remain the grand challenge.
