Theoretical Studies of Ocean Boundary Currents

将使用分析方法和简单的数值模型研究大尺度涡旋在确定象西部边界流这样的海洋喷流的结构和夹带方面所起的作用。本研究的具体目标是：(1)解释从旋转实验室储罐壁上的源产生的正压射流的行为；(2)了解通常入射到陆坡/陆架区域壁面射流的分岔动力学；(3)确定了佛罗里达流等大陆边界流最大平均近海切变的增加；(4)将剪切流中“自传播”正压涡的线性理论推广到非线性情况。

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.
