项目摘要
0095971/RhinesThe project addresses two questions associated with the spin-up of rotating, stratified fluids like the ocean. The first concerns the effect of nonlinear coupling between the Ekman pumping induced by wind stress curl and the vorticity of the interior geostrophic flow generated by the Ekman pumping. The second concerns the generation of convective and inertial instabilities by the advection of horizontal density gradients in the Ekman layer by Ekman fluxes, together with the vertical mixing these instabilities produce. The work consists of the development and study of analytical and numerical models of three-dimensional representations of these phenomena together with experiments to reproduce these phenomena in the laboratory and to test the theoretical and numerical predictions. Numerical simulations will be extended to a model of coastal upwelling. The work builds on two-dimensional theoretical and numerical models of these processes.
0095971/Rhines该项目解决了两个与旋转相关的问题,分层流体如海洋。 第一个问题是风应力旋度引起的Ekman抽吸与Ekman抽吸产生的内地转流涡度之间的非线性耦合效应。 第二个问题涉及的对流和惯性不稳定性的产生的水平密度梯度的平流在埃克曼层的埃克曼通量,连同这些不稳定性产生的垂直混合。 这项工作包括开发和研究这些现象的三维表示的分析和数值模型,以及在实验室中重现这些现象并测试理论和数值预测的实验。 数值模拟将扩展到沿海上升流模式。 这项工作建立在这些过程的二维理论和数值模型。
