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.

将进行分析和数值研究，以检查剪切波和无旋波对朗缪尔细胞形成的作用。产生涡旋的不稳定机制以Craik-Leibovich 2型机制为基础，因为海洋学观测揭示了这些方程的局限性，所以它们将不用于描述流动。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。海洋和实验室观测的实际平均海流将用于估计混合层内的热量和动量输送。这项工作是重要的，因为朗缪尔环流似乎是一个重要的混合机制，在海气界面。
