海洋科学学术讲座预告第435期：Oceanic Turbulent Cascades: the Role of Eddy-Wave Interactions and the Pathways to Dissipation

报告内容简介：

      The ocean circulation is characterized by diverse turbulence regimes that span a vast range of spatial and temporal scales.Understanding how these distinct turbulence regimes and their interactions lead to the observed spatiotemporal distributions of energy, heat, and tracers in the ocean is essential for predicting circulation adjustments and their effects on the climate system. In this talk, I will discuss how the interplay between geostrophic turbulence, submesoscale turbulence, boundary layer turbulence, and weak-wave turbulence shapes the ocean circulation, with a particular focus on cross-scale energy transfer and dissipation patterns. I will also discuss how a comprehensive approach—combining analytical theory, circulation models of varying complexity, and carefully designed field experiments—can ultimately improve the representation of these turbulent processes in climate models.
