9811939勒隆该项目是为了对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等问题进行数值研究。将进行一系列面向过程的数值模拟。第一个研究将扩展正在进行的涡旋模式引起的剪切增强弥散的研究。第二项研究将集中在惯性重力波不稳定开始后位涡的产生。第三项研究将在中尺度模式中测试涡模动力学的参数化。第四个研究将研究背景涡旋模式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.
