A Methodology to Quantify Interscale Energy Transfer at Solid Boundaries
Lennard Miller
Far away from solid boundaries, energy can be transferred between different flow scales due to the non-linear self-advection of velocity. This energy transfer can be quantified usi…
Enhanced Gulf Stream Path Variability Under Intensified Stratification
Lennard Miller, Antoine Venaille, Stephane Popinet +1
Increased upper-ocean stratification is an unavoidable consequence of global warming and will strongly impact the structure of ocean currents. Using a high-resolution ocean model,…
The Impact of Stratification on Surface-Intensified Eastward Jets in Turbulent Gyres
Lennard Miller, Bruno Deremble, Antoine Venaille
This study examines the role of stratification in the formation and persistence of eastward jets (like the Gulf Stream and Kuroshio currents). Using a wind-driven, two-layer quasi-…
Gyre Turbulence
Lennard Miller, Antoine Venaille, Bruno Deremble
The exploration of a two-dimensional wind-driven ocean model with no-slip boundaries reveals the existence of a turbulent asymptotic regime where energy dissipation becomes indepen…
