Mixing and the Production of Potential Vorticity at Small Scales in the Ocean

小行星9811939 该项目的目的是数值研究有关小尺度位涡的起源及其对海洋小尺度动力学和混合过程的影响的问题。 将进行一系列面向过程的数值模拟。 第一项研究将扩展目前正在进行的研究剪切增强分散由于涡模式。 第二项研究将侧重于惯性重力波不稳定开始后位涡的产生。 第三项研究将测试中尺度模型中涡旋模式动力学的参数化。 第四项研究将探讨背景涡模对内波场中能量传递的影响。

9811939 Lelong The project is for a numerical study of issues concerning the origin of small-scale potential vorticity and its effects on dynamics and mixing processes of the oceanic small-scale. A series of process-oriented numerical simulations will be performed. The first study will extend the ongoing research on shear-enhanced dispersion due to vortical modes. The second study will focus on the generation of potential vorticity following onset of instability of an inertia-gravity wave. The third study will test parameterizations for vortical-mode dynamics in meso-scale models. And the fourth study will investigate the effect of background vortical modes on energy transfers in an internal wave field.
