A new method for isolating turbulent states in transitional stratified plane Couette flow
(Cambridge University PressJournal of Fluid Mechanics, 2016-10-26)
We present a new adaptive control strategy to isolate and stabilize turbulent states in transitional, stably stratified plane Couette flow in which the gravitational acceleration (non-dimensionalized as the bulk Richardson ...
Robust identification of dynamically distinct regions in stratified turbulence
(Cambridge University PressJournal of Fluid Mechanics, 2016-10-18)
We present a new robust method for identifying three dynamically distinct regions in a stratified turbulent flow, which we characterise as quiescent flow, intermittent layers and turbulent patches. The method uses the ...
Spontaneous Wave Generation at Strongly Strained Density Fronts
(American Meteorological SocietyJournal of Physical Oceanography, 2016-06-23)
A simple analytical model is presented describing the spontaneous generation of inertia–gravity waves at density fronts subjected to strong horizontal strain rates. The model considers fronts of arbitrary horizontal and ...
Turbulent mixing, restratification, and phytoplankton growth at a submesoscale eddy
(WileyGeophysical Research Letters, 2016-05-13)
High-resolution large-eddy simulations are used to study the influence of submesoscale mixed layer instability and small-scale turbulence on phytoplankton growth in light-limited conditions. Four simulations are considered ...
