Understanding how turbulence leads to the enhanced irreversible transport of heat and
other scalars such as salt and pollutants in density-stratified fluids is a fundamental and …

Flow in a stably stratified environment is characterized by anisotropic and intermittent
turbulence and wavelike motions of varying amplitudes and periods. Understanding …

Instabilities are present in all natural fluids from rivers to atmospheres. This book considers
the physical processes that generate instability. Part I describes the normal mode …

The convective primary amplification of a forced two-dimensional perturbation initiates the
formation of essentially two-dimensional large-scale vortices in a laminar separation bubble …

Motivated by the importance of small-scale turbulent diapycnal mixing to the closure of the
large-scale meridional overturning circulation (MOC) of the oceans, we focus on a model …

We present a new, simple and physically motivated parameterization, based on the ratio of
Thorpe and Ozmidov scales, for the irreversible turbulent flux coefficient. Importantly …

Continuously forced, stratified shear flows occur in many geophysical systems, including
flow over sills, through fjords and at the mouths of rivers and estuaries. These continuously …

We consider numerically the transition to turbulence and associated mixing in stratified
shear flows with initial velocity distribution. Despite their vastly different mechanics (ie …

Turbulent shear layers in a uniformly stratified background: DNS at high Reynolds number
Page 1 J. Fluid Mech. (2021), vol. 916, A42, doi:10.1017/jfm.2021.212 Turbulent shear layers …

In a stably stratified shear layer, multiple competing instabilities produce sensitivity to small
changes in initial conditions, popularly called the butterfly effect (as a flapping wing may …
