9415512 Samelson This project is a theoretical and numerical investigation into the coupled dynamics of the large- and meso-scale circulation. The theoretical and conceptual work will be based on two sets of coupled equations, the planetary- geostrophic (PG) and quasi-geostrophic (QG) equations. The first part of the study focuses on the analysis of the subpolar gyre circulation in numerical solutions of the PG equations without any effects of mesocale eddies (uncoupled from the QG component). Double-gyre wind- and buoyancy- forced solutions of the PG model will be considered, analyzed in detail, and compared to existing theories of the gyre regimes. The second and third parts of the study will continue with the analysis of the coupled PG-QG model and will focus on the interaction between the mesoscale and large-scale flows.

9415512 Samelson该项目是对大尺度和中尺度环流耦合动力学的理论和数值研究。 理论和概念工作将基于两套耦合方程，行星-地转（PG）和准地转（QG）方程。 研究的第一部分着重于分析PG方程数值解中的副极地环流环流，而没有任何中尺度涡旋的影响（与QG分量解耦）。 双环流风和浮力强迫PG模型的解决方案将被考虑，详细分析，并比较现有的理论的环流制度。 第二和第三部分的研究将继续与耦合PG-QG模式的分析，并将集中在中尺度和大尺度流动之间的相互作用。
