Langmuir Circulations Beneath Growing or Deforming Surface Waves

本文将对剪切波和无旋波在朗缪尔细胞形成过程中的作用进行分析和数值研究。产生涡旋的不稳定机制是以Craik-Leibovich 2型机制为基础的，因为海洋观测揭示了这些方程的局限性，它们将不被用来描述气流。当C-L方程不适用于海洋表面混合层时，将采用Andrews和McIntyre的广义拉格朗日平均方程来定义。实际平均海流和实验室观测将用于估计混合层内的热、质量和动量输运。这项工作很重要，因为朗缪尔环流似乎是海气界面的重要混合机制。

An analytical and numerical study to examine the role of shear and irrotational waves on the formation of Langmuir cells will be conducted. The instability mechanism giving rise to the vortices has as its basis the Craik-Leibovich type 2 mechanism, because oceanographic observations bring to light limitations with these equations, they will not be used to describe the flow. Instead the generalized Lagrangian mean equations of Andrews and McIntyre will employed to define when the C-L equation is not applicable to the ocean surface mixed layer. Actual mean currents from ocean and laboratory observations will be used to estimate heat mass and momentum transport within the mixed layer. This work is important because Langmuir circulations appear to be an important mixing mechanism at the air-sea interface.
