Abstract: The structure of boundary currents formed from intermediately dense water introduced into a rotating, stably stratified, two‐layer environment is investigated in a series of laboratory experiments, performed for Froude numbers ranging from 0.01 to 1. The thickness and streamwise velocity profiles in quasi‐steady currents are measured and found to agree with analytic solutions and numerical models. A sloping boundary in a stratified background results in robust stability at all…

Stable and unstable shear modes of rotating parallel flows in shallow water
This article considers the instabilities of rotating, shallow-water, shear flows on an equatorial β-plane. Because of the free surface, the motion is horizontally divergent and the energy density is
Wave propagation and growth on a surface front in a two-layer geostrophic current
We study analytically and numerically small amplitude perturbations of a geostrophically balanced semi-infinite layer of light water having a surface front and lying above a heavier layer of finite
Stability of rotating shear flows in shallow water
Asymptotic methods are used to determine the dispersion equation for disturbances of rotating parallel flows in shallow water. From this equation the unstable modes and their growth rates are
Laboratory observations of a gravity current on a sloping bottom: the generation of shelf waves
A source of light water was started along the outside vertical wall of a cylindrical tank in uniform rotation. Like wall gravity currents studied previously, it had a nose which detrained eddies as
A powerful local shear instability in weakly magnetized disks. I - Linear analysis. II - Nonlinear evolution
A broad class of astronomical accretion disks is presently shown to be dynamically unstable to axisymmetric disturbances in the presence of a weak magnetic field, an insight with consequently broad

On the stability of magnetized accretion discs
The shear instability of differentially rotating magnetized accretion discs is formulated as an eigenvalue problem. A monotonic instability caused by the presence of weak vertical magnetic fields,
