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…
Force balance in numerical geodynamo simulations: a systematic study
T. Schwaiger, T. Gastine, J. Aubert
Dynamo action in the Earth's outer core is expected to be controlled by a balance between pressure, Coriolis, buoyancy and Lorentz forces, with marginal contributions from inertia…
Geomagnetic acceleration and rapid hydromagnetic wave dynamics in advanced numerical simulations of the geodynamo
Julien Aubert
Geomagnetic secular acceleration is a unique window on the dynamics taking place in Earth's core. In this study, the behaviours of the secular acceleration and underlying core dyna…
