What can asymptotic expansions tell us about large-scale quasi-geostrophic anticyclonic vortices?
asymptotic expansions large-scale quasi-geostrophic anticyclonic vortices
2009/11/16
The problem of the large-scale quasi-geostrophic anticyclonic vortices is studied in the framework of the baratropic rotating shallow- water equations on the β-plane. A systematic approach based on th...

Results from an experimental study of vortices in a rotating shear layer are presented. The data are in the form of maps of the instantaneous horizontal velocity field obtained by a particle tracking ...
Results on the formation and propagation of electron phase space vortices from laboratory experiments are summarized. The electron phase space vortices were excited in a strongly magnetized Q-machine ...
Downstream and soaring interfaces and vortices in 2-D stratified wakes and their impact on transport of contaminants
Downstream soaring interfaces vortices 2-D stratified wakes transport of contaminants

The flow of continuously stratified fluids past obstacles was studied analytically, numerically, and experimentally. The obstacles discussed here include a flat strip, aligned with the flow, inclined ...
Evolution of localized vortices in the presence of stochastic perturbations
Evolution of localized vortices presence of stochastic perturbations
2009/11/9
We consider the evolution of a distribution of N identical point vortices when stochastic perturbations in the Hamiltonian are present. It is shown that different initial configurations of vorticity w...
Plankton blooms in vortices:the role of biological and hydrodynamic timescales
Plankton blooms vortices biological and hydrodynamic timescales
2009/11/3
We study the interplay of hydrodynamic mesoscale structures and the growth of plankton in the wake of an island, and its interaction with a coastal upwelling. Our focus is on a mechanism for the emerg...
