Role of submesoscale instabilities in the lateral transport and mixing of freshwater

淡水的横额转移将使用源自混沌动力系统研究的拉格朗日技术进行研究，特别是通过识别三维有限时间和有限分离李雅普诺夫指数（分别为FTLEs和FSLEs）。FTLEs和FSLEs可以绘制搅拌图和检测混合障碍，这对淡水的横向和垂直转移很重要。将使用北大西洋高分辨率的实际数值模拟来计算fft - les和FSLEs。它们的分布将与淡水的分布进行比较。结果将与Forschungsgruppe内其他项目观测到的横向混合结果进行比较。

The cross-frontal transfer of freshwater will be studied using Lagrangian techniques derived from the study of chaotic dynamical systems, in particular through the identification of three dimensional Finite Time and Finite Separation Lyapunov Exponents (FTLEs and FSLEs respectively). FTLEs and FSLEs can provide a mapping of stirring and the detection of mixing barriers, that can be important for the lateral and vertical transfer of freshwater. FTLEs and FSLEs will be calculated using realistic numerical simulations of the North Atlantic at high resolution. Their distribution will be compared with the distribution of freshwater. Results will be compared with the results of lateral mixing from the observations from other projects within the Forschungsgruppe.
