A statistical physics and dynamical systems perspective on geophysical extreme events
Davide Faranda, Gabriele Messori, Tommaso Alberti +14
Statistical physics and dynamical systems theory are key tools to study high-impact geophysical events such as temperature extremes, cyclones, thunderstorms, geomagnetic storms and…
Maximum Kolmogorov-Sinai entropy vs minimum mixing time in Markov chains
Martin Mihelich, Berengere Dubrulle, Didier Paillard +2
Many modern techniques employed in physics, such a computation of path integrals, rely on random walks on graphs that can be represented as Markov chains. Traditionally, estimates…
Statistical optimization for passive scalar transport: maximum entropy production vs maximum Kolmogorov-Sinay entropy
Martin Mihelich, Berengere Dubrulle, Didier Paillard +1
We derive rigorous results on the link between the principle of maximum entropy production and the principle of maximum Kolmogorov-Sinai entropy using a Markov model of the passive…
Vertical Temperature Profiles at Maximum Entropy Production with a Net Exchange Radiative Formulation
Corentin Herbert, Didier Paillard
Like any fluid heated from below, the atmosphere is subject to vertical instability which triggers convection. Convection occurs on small time and space scales, which makes it a ch…
Statistical mechanics of quasi-geostrophic flows on a rotating sphere
Corentin Herbert, Bérengère Dubrulle, Pierre-Henri Chavanis +1
Statistical mechanics provides an elegant explanation to the appearance of coherent structures in two-dimensional inviscid turbulence: while the fine-grained vorticity field, descr…
Phase transitions and marginal ensemble equivalence for freely evolving flows on a rotating sphere
Corentin Herbert, Bérengère Dubrulle, Pierre-Henri Chavanis +1
The large-scale circulation of planetary atmospheres like that of the Earth is traditionally thought of in a dynamical framework. Here, we apply the statistical mechanics theory of…
Statistical mechanics of Fofonoff flows in an oceanic basin
A. Naso, P. H. Chavanis, B. Dubrulle
We study the minimization of potential enstrophy at fixed circulation and energy in an oceanic basin with arbitrary topography. For illustration, we consider a rectangular basin an…
Statistical mechanics of two-dimensional Euler flows and minimum enstrophy states
A. Naso, P. H. Chavanis, B. Dubrulle
A simplified thermodynamic approach of the incompressible 2D Euler equation is considered based on the conservation of energy, circulation and microscopic enstrophy. Statistical eq…
Relaxation equations for two-dimensional turbulent flows with a prior vorticity distribution
P. H. Chavanis, A. Naso, B. Dubrulle
Using a Maximum Entropy Production Principle (MEPP), we derive a new type of relaxation equations for two-dimensional turbulent flows in the case where a prior vorticity distributi…
Scaling laws and vortex profiles in 2D decaying turbulence
Jean-Philippe Laval, Pierre-Henri Chavanis, Bérengère Dubrulle +1
We use high resolution numerical simulations over several hundred of turnover times to study the influence of small scale dissipation onto vortex statistics in 2D decaying turbulen…
