Abstract: We use statistical models of turbulence with ?eddy damping? (EDQNM) in order to study the problem of predictability of freely evolving two- and three-dimensional isotropic turbulent flows. The application of statistical ...

Abstract: It is well established that at low Rossby and Froude numbers modes possessing potential vorticity behave differently from gavity-inertial wave modes. Wave energy cascades relatively more efficiently downscale to the ...

Abstract: Baroclinic instabilities of jet flows are investigated by means of numerical simulations of the nonhydrostatic Boussinesq equations on the f plane. Frontal small scales are accurately described thanks to precise numerical ...
