Motional induction in Ganymede's ocean
Simon Cabanes, Thomas Gastine, Alexandre Fournier
We investigate the magnetic signature of oceanic circulation in Ganymede's subsurface ocean using kinematic induction modeling. Our approach couples zonal jet flows from rotating t…
Online learning of subgrid-scale models for quasi-geostrophic turbulence in planetary interiors
Hugo Frezat, Thomas Gastine, Alexandre Fournier
Machine learning approaches to subgrid-scale (SGS) modelling are now well established in atmospheric and oceanic applications. Among these, online end-to-end learning, where the di…
Core-surface kinematic control of polarity reversals in advanced geodynamo simulations
Julien Aubert, Maylis Landeau, Alexandre Fournier +1
The geomagnetic field has undergone hundreds of polarity reversals over Earth's history, at a variable pace. In numerical models of Earth's core dynamics, reversals occur with incr…
Zonostrophic turbulence in the subsurface oceans of the Jovian and Saturnian moons
S. Cabanes, T. Gastine, A. Fournier
In order to characterize the global circulation of the subsurface ocean of Jovian and Saturnian moons, we analyze the properties of 21 three-dimensional simulations of Boussinesq t…
Fingering convection in a spherical shell
T. Tassin, T. Gastine, A. Fournier
We use 123 three dimensional direct numerical simulations to study fingering convection in non-rotating spherical shells. We investigate the scaling behaviour of the flow lengthsca…
