This proposal is to continue investigation on topics of large scale circulation theory. With the aid of numerical and analytical models, Ierley has determined the effect of boundary conditions, western boundary layers and inertial jets on the vorticity balance of quasi-geostrophic (QG) ocean models. The main aspect of these studies is to comprehend the physical reasons for the features exhibited by the numerical solutions. Ierley has produced very valuable contributions to the theory of ocean circulation with his analysis of "q-driven" models, models in which the interior flow is determined by the advection and diffusion of potential vorticity. He will analyze very high resolution, low viscosity QG model solutions which show western boundary separation and intense inertial recirculation. This analysis is critical to interpret results of ocean models used for climatic studies.

本提案是继续对大尺度环流理论课题进行研究。借助数值和分析模型，Ierley 确定了边界条件、西部边界层和惯性喷流对准地转 (QG) 海洋模型涡度平衡的影响。这些研究的主要方面是理解数值解所表现出的特征的物理原因。 伊尔利通过对“q 驱动”模型的分析，对海洋环流理论做出了非常有价值的贡献，在该模型中，内部流动是由位涡的平流和扩散决定的。他将分析非常高分辨率、低粘度的 QG 模型解决方案，该模型显示了西边界分离和强烈的惯性再循环。该分析对于解释用于气候研究的海洋模型的结果至关重要。
