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 authors investigate atmospheric internal gravity waves (IGWs): their generation and
induction of global intermittent turbulence in the nocturnal stable atmospheric boundary …

In this article, we study the nonlinear higher order of extended KdV equation with free
surface displacement. The modified exponential rational function method is used in order to …

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

Finite-amplitude manifestations of stratified shear flow instabilities and their spatio-temporal
coherent structures are believed to play an important role in turbulent geophysical flows …

Most idealized studies of stratified shear instabilities assume that the shear interface and the
buoyancy interface are coincident. We discuss the role of asymmetry on the evolution of …

The vertical transport of sediment from particle-laden flows in marine settings can be
enhanced by a settling-driven convective instability. The presence of a horizontal velocity …

In low winds (≲ 2 ms− 1), diurnal warm layers form, but shear in the near-surface jet is too
weak to generate shear instability and mixing. In high winds (≳ 8 ms− 1), surface heat is …
