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 …

Baroclinic instability is that of flows in a rotating stratified fluid with a vertical velocity shear.
The generation of large-scale vortical flows in the atmospheres of Earth and other planets is …

The Earth is a thermal engine generating the fundamental processes of geomagnetic field,
plate tectonics and volcanism. Large amounts of heat are permanently lost at the surface …

In this work the authors draw upon their expertise in geophysical and astrophysical MHD to
explore the motion of electrically conducting fluids, the so-called dynamo effect, and …

A previously unknown instability creates space-filling lattices of 3D vortices in linearly stable,
rotating, stratified shear flows. The instability starts from an easily excited critical layer. The …

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 …

Abstract Decades ago S. Lundquist, S. Chandrasekhar, PH Roberts and RJ Tayler first
posed questions about the stability of Taylor–Couette flows of conducting material under the …

This paper investigates the stability of a columnar vortex in an inviscid stratified fluid. By
means of a WKBJ analysis for large axial wave number, we demonstrate that the normal …

We present the stability analysis of a plane Couette flow which is stably stratified in the
vertical direction orthogonal to the horizontal shear. Interest in such a flow comes from …

Most flows in nature and engineering are turbulent because of their large velocities and
spatial scales. Laboratory experiments on rotating quasi-Keplerian flows, for which the …
