Odier, T. Dauxois, 2012. Experimental
observation of strong mean flows generated by internal gravity waves
- in review for Physics of Fluids, 7
pages .pdf
Shows
that a monochromatic wave beam propagating in a stratified fluid
induces a robust and strong jet flowing outward the wave generator. |

statistical equilibrium states above topography anomalies. - Journal of Fluid
Mechanics,

pages
.pdf
Shows
that in presence of a sufficiently large topographic bump, an initial
surface-intensified random velocity field evolves towards a
bottom-trapped anticyclonic mean flow, which is predicted by
statistical mechanics. |

role of beta effect in barotropization processes - in review for Journal of Fluid
Mechanics,

pages .pdf
Shows
that the presence of planetary vorticity gradients favors the tendendy
to spread the energy on the vertical in stratified quasi-geostrophic
turbulent flows, and that statistical mechanics arguments account for
this phenomenon. |

turbulence in the ocean:
analysis with primitive equation and quasi-geostrophic simulations -

pages .pdf
Tests
the
hypothesis that oceanic eddies result from
local baroclinic instabilities, and examines the factors determining
their distribution, length scale, magnitude and structure. |

variability of large scale oceanic flows above topography anomalies. - Geophysical Research Letters, 6
pages .pdf , compte
rendu sur le site de l'insu
A stochastic
mechanism is proposed to interpret the dynamics of
eddy-driven recirculations above closed contours of bottom topography.
This may account for the observed low frequency variability of the
Zapiola anticyclone. |

mechanics of
two-dimensional and
geophysical flows - Physics Reports, 130 pages .pdf
Review
paper with emphasis on Robert-Sommeria-Miller
equilibrium theory. Former statistical approaches are also
discussed, as well as current developments in out of equilibrium
context. |

Venaille, F. Bouchet, 2011. Oceanic
rings and jets as
statistical equilibrium states - Journal of Physical Oceanography,15
pages .pdf
Using statistical
mechanics arguments, oceanic rings are interpreted as "bubbles" of
homogenized potential vorticity. It may provide an explanation for
their
ubiquity, their shape, and their drift. |

Bouchet, 2011. Solvable
phase diagrams and ensemble inequivalence for two-dimensional and
geophysical turbulent flows - Journal of Statistical Physics, 35
pages .pdf
Companion
paper of PRL09 below. Discusses symmetry breaking associated with
the generic occurrence of ensemble inequivalence, and the surprising
effect of the Rossby radius of deformation (a screening length
scale). |
A.4 A. Venaille, F. Bouchet, 2009. Statistical
Ensemble Inequivalence and Bicritical Points for Two-Dimensional Flows
and Geophysical Flows - Physical Review Letters, 4 pages
.pdf
It
is shown that statistical ensemble inequivalence and negative
specific heat occur for a wide class of models and parameters,
including Fofonoff flows, and
are related to previously observed phase transitions in the flow
topology. |

Is mixing a self-convolution process ? - Physical Review Letters, 4 pages
.pdf
Experimental
tests of the self-convolution model for mixing of a passive tracer. It
is shown that
the model is doing well at sufficiently late stage of
mixing. |

A dynamical equation for the distribution of a scalar advected by
turbulence. - Physics

Provides
phenomenological arguments showing that the mixing of a
passive tracer through turbulent cascades may be represented as
a succession of self-convolutions of the tracer distribution. |

Synchronization and coordination of sequences in two neural ensembles.-
Physical
Review E, 8 pages .pdf
Synchronization
properties emerging from the coupling
of two chaotic systems are investigated. This
illustrates how a mollusk can scan randomly an area to find a
prey, while keeping some efficiency in swimming.
