9314140, PI-Flierl: This proposal is directed to the study of the meandering and eddy production of western boundary currents, both in the case when they flow in mid-ocean (i.e. the Gulf Stream) and when they follow the coast (i.e. The East Australian Current). While these motions are generally ascribed to instabilities of the flow, they generally occur in the form of pulses and develop both in space and time. This project will address the linear and non-linear dynamics of pulses and other perturbations on jets. The work will combine a number of analytical and numerical techniques. The different perspectives offered by the various process models will complement each other to provide a more detailed picture of the dynamics. The results will suggest new approaches for analyzing the oceanic data on meandering and eddy processes.

[9314140] PI-Flierl：该提案是针对西部边界流的蜿蜒和涡流产生的研究，无论是在海洋中部（即墨西哥湾流）流动的情况下，还是在它们沿着海岸流动的情况下（即东澳大利亚流）。虽然这些运动通常归因于流动的不稳定性，但它们通常以脉冲的形式发生，并在空间和时间上发展。该项目将解决脉冲的线性和非线性动力学以及射流上的其他扰动。这项工作将结合许多分析和数值技术。各种流程模型提供的不同视角将相互补充，以提供更详细的动态图像。研究结果将为曲流和涡流过程的海洋资料分析提供新的途径。
