Contributions to the geomagnetic secular variation from a reanalysis of core surface dynamics

Olivier Barrois, Nicolas Gillet, Julien Aubert

We invert for motions at the surface of Earth's core under spatial and temporal constraints that depart from the mathematical smoothings usually employed to ensure spectral converg…

On the convergence of the MLE as an estimator of the learning rate in the Exp3 algorithm

Julien Aubert, Luc Lehéricy, Patricia Reynaud-Bouret

When fitting the learning data of an individual to algorithm-like learning models, the observations are so dependent and non-stationary that one may wonder what the classical Maxim…

The interplay of fast waves and slow convection in geodynamo simulations nearing Earth's core conditions

Julien Aubert, Nicolas Gillet

Ground observatory and satellite-based determinations of temporal variations in the geomagnetic field probe a decadal to annual time scale range where Earth's core slow, inertiales…

Relating force balances and flow length scales in geodynamo simulations

Tobias Schwaiger, Thomas Gastine, Julien Aubert

In fluid dynamics, the scaling behaviour of flow length scales is commonly used to infer the governing force balance of a system. The key to a successful approach is to measure len…

Dynamo-based limit to the extent of a stable layer atop Earth's core

Thomas Gastine, Julien Aubert, Alexandre Fournier

The existence of a stably stratified layer underneath the core-mantle boundary (CMB) has been recently revived by corroborating evidences coming from seismic studies, mineral physi…

Approaching Earth's core conditions in high-resolution geodynamo simulations

J. Aubert

The geodynamo features a broad separation between the large scale at which Earth's magnetic field is sustained against ohmic dissipation and the small scales of the turbulent and e…
