Breakdown of chiral symmetry during saturation of the Tayler instability
Breakdown of chiral symmetry saturation of the Tayler instability Fluid Dynamics
2012/4/19
We study spontaneous breakdown of chiral symmetry during the nonlinear evolution of the Tayler instability. We start with an initial stationary state of zero helicity. Within linearized perturbation c...
Baroclinic instability of a symmetric,rotating,stratified flow:a study of the nonlinear stabilisation mechanisms in the presence of viscosity
Baroclinic instability nonlinear stabilisation mechanisms presence of viscosity
2009/11/12
This paper presents the analysis of symmetric circulations of a rotating baroclinic flow, forced by a steady thermal wind and dissipated by Laplacian friction. The analysis is performed with numerical...

Here are presented the results of experimental and theoretical studies on a stability of zonal geostrophic flows in the rotating layer of the shallow water. In the experiments, a special apparatus by ...
Synchronization and chaos control in a periodically forced quasi-geostrophic two-layer model of baroclinic instability
Synchronization chaos control quasi-geostrophic two-layer model baroclinic instability
2009/11/9
Cyclic forcing on many timescales is believed to have a significant effect on various quasi-periodic, geophysical phenomena such as El Niño, the Quasi-Biennial Oscillation, and glacial cycles. ...
Nonlinear instability and sensitivity of a theoretical grassland ecosystem to finite-amplitude perturbations
Nonlinear instability theoretical grassland ecosystem finite-amplitude perturbations
2009/11/3
Within a theoretical model context, the sensitivity and instability of the grassland ecosystem to finite-amplitude perturbations are studied. A new approach of conditional nonlinear optimal perturbati...

Non-propagating magnetic hole solutions in anisotropic plasmas near the mirror instability threshold are investigated in numerical simulations of a fluid model that incorporates linear Landau damping ...
A delay differential model of ENSO variability:parametric instability and the distribution of extremes
delay differential model ENSO variability parametric instability distribution of extremes
2009/10/30
We consider a delay differential equation (DDE) model for El-Niño Southern Oscillation (ENSO) variability. The model combines two key mechanisms that participate in ENSO dynamics: delayed negat...
Synchronization in a coupled two-layer quasigeostrophic model of baroclinic instability–Part 1:Master-slave configuration
two-layer quasigeostrophic model baroclinic instability Master-slave configuration
2009/10/30
Synchronization is studied using a pair of diffusively-coupled, two-layer quasi-geostrophic systems each comprising a single baroclinic wave and a zonal flow. In particular, the coupling between the s...
