OCE 96-17848 Flierl The project will apply analytical and numerical models to investigate the development of disturbances in oceanic "jets" associated with western boundary currents such as the Gulf Stream. Several dynamically important extensions to existing work in the field will be investigated: Baroclinic effects on jet stability will be addressed by including realistic horizontal and vertical structures in the models. The nonlinear evolution of the jet and of jet instabilities will be considered in the presence of the mean flow recirculation which surrounds the jet. Variations in the jet and changes in the development of instabilities caused by the proximity of a coastal boundary will be examined.

OCE 96-17848 Flierl 该项目将应用分析和数值模型，调查与墨西哥湾流等西部边界流有关的海洋“喷流”扰动的发展情况。几个动态的重要扩展，在该领域的现有工作将进行调查：斜压射流稳定性的影响将解决包括现实的水平和垂直结构的模型。 射流和射流不稳定性的非线性演化将被认为是在射流周围的平均流再循环的存在下。急流的变化和沿海边界附近引起的不稳定性发展的变化将被检查。
