Stern OCE-9529261 The role that large scale eddies play in determining the structure of, and entrainment in, oceanic jets like Western Boundary Currents will be studied using analytical methods and simple numerical models. The specific objectives of this research are: (1) to explain the behavior of barotropic jets emerging from a source on the wall of a rotating laboratory tank; (2) to understand the bifurcation dynamics of a wall jet normally incident on a continental slope/shelf region; (3) to determine the increase in maximum mean inshore shear of continental boundary currents like the Florida Current; and (4) to extend the linear theory of a "self propagating" barotropic eddy in a shear flow to the non-linear case.

Stern OCE-9529261大尺度涡流在确定大气结构中的作用， 卷吸，海洋射流，如西部边界流将研究使用 分析方法和简单的数值模型。这一具体目标 主要研究内容有：（1）解释正压急流的运动规律 在旋转实验室水槽的壁上;（2）了解分叉动力学 通常入射到大陆坡/大陆架区域的贴壁射流; ⑶确定 大陆边界流（如 佛罗里达海流;（4）推广了“自传播”的线性理论 正压涡在切变流的非线性情况。
