简介：重力的势能(GPE)变化由于horizontal/isopycnal旋涡散开和移流被检验。Horizontal/isopycnal旋涡散开概念上被分开成二步：激动人心并且subscale散开。与这二步联系的GPE变化被分析。另外，GPE变化由于激动人心并且在Eulerian坐标与horizontal/isopycnal移流联系的subscale散开被分析。这些公式为世界海洋被用于SODA数据。我们的分析显示在Eulerian坐标的horizontal/isopycnal移流能在模型介绍大人工的散开。在isopycnal坐标的GPE来源/水池仔细被连接到物理性质分发，这被显示出，例如温度，咸度和速度。与z协调比较，GPE来源/水池由于与isopycnal散开/移流联系的stirring/cabbeling是小得多的。尽管isopycnal坐标可以以处理侧面的散开是一种更好的选择，在传统的Eulerian坐标的移流术语能由于与移流联系的cabbeling生产GPE的人工的来源。减少如此的数字错误仍然是宏大挑战。
