Estimation of the functional form of subgrid-scale schemes using ensemble-based data assimilation: a simple model experiment
(Wiley, 2016-10-02)
Oceanic and atmospheric global numerical models represent explicitly the large‐scale dynamics while the smaller‐scale processes are not resolved, so that their effects in the large‐scale dynamics are included through ...
Estimation of the functional form of subgrid-scale parametrizations using ensemble-based data assimilation : a simplemodel experiment
(Royal Meteorological Society, 2016)
Oceanic and atmospheric global numerical models represent explicitly the large-scale dynamics while the smaller-scale processes are not resolved, so that their effects in the large-scale dynamics are included through ...

High Reynolds number magnetohydrodynamic turbulence using a Lagrangian model
(American Physical Society, 2011-07)
With the help of a model of magnetohydrodynamic (MHD) turbulence tested previously, we explore high Reynolds number regimes up to equivalent resolutions of 60003 grid points in the absence of forcing and with no imposed ...

Three regularization models of the Navier-Stokes equations
(American Institute of Physics, 2008-03)
We determine how the differences in the treatment of the subfilter-scale physics affect the properties of the flow for three closely related regularizations of Navier-Stokes. The consequences on the applicability of the ...
Inverse cascades and α effect at a low magnetic Prandtl number
(American Physical Society, 2007-12)
Dynamo action in a fully helical Arn'old-Beltrami-Childress flow is studied using both direct numerical simulations and subgrid modeling. Sufficient scale separation is given in order to allow for large-scale magnetic ...
