In a context of global change and increasing anthropic pressure on the environment,
monitoring the Earth system and its evolution has become one of the key missions of …

Geomagnetic observations from satellites have highlighted interannual variations in the rate
of change of the magnetic field originating from Earth's core. Downward continued to the …

We present an attempt to reach realistic turbulent regime in direct numerical simulations of
the geodynamo. We rely on a sequence of three convection-driven simulations in a rapidly …

Rayleigh–Bénard convection in rotating spherical shells can be considered as a simplified
analogue of many astrophysical and geophysical fluid flows. Here, we use three …

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 …

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 length …

Abstract Changes in the Earth's rotation are deeply connected to fluid dynamical processes
in the outer core. This connection can be explored by studying the associated Earth …

We use rotating convection simulations in a thin spherical shell to study fluid dynamics in
subsurface oceans of icy moons. We find two types of persistent results, characterized by …

Turbulent convection is thought to act as an effective viscosity in dam** equilibrium tidal
flows, driving spin and orbital evolution in close convective binary systems. Compared to …

The outer core of the Earth, filled with electrically conducting fluid, undergoes
thermochemical convection due to super-adiabatic temperature gradients. Near the core …
