Few areas of geophysics are today progressing as rapidly as basic geomagnetism, which
seeks to understand the origin of the Earth's magnetism. Data about the present …

The heat transfer scaling theories for Rayleigh‐Bénard convection (RBC) are reviewed and
discussed for configurations with and without rotation and magnetic fields. Scaling laws are …

Turbulent Rayleigh-Bénard convection displays a large-scale order in the form of rolls and
cells on lengths larger than the layer height once the fluctuations of temperature and velocity …

Self-sustained convective dynamos in planetary systems operate in an asymptotic regime of
rapid rotation, where a balance is thought to hold between the Coriolis, pressure, buoyancy …

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 …

Turbulent, rapidly rotating convection has been of interest for decades, yet there exists no
generally accepted scaling law for heat transfer behaviour in this system. Here, we develop …

The state of knowledge and understanding of planetary magnetic fields is reviewed. All of
the planets, with the possible exception of Venus, have had active dynamos at some time in …

We present laboratory and numerical models investigating the behavioural regimes of
rapidly rotating convection in high-latitude planetary core-style settings. Our combined …

We numerically explore convection and general circulation of an ocean, encased in a
spherical shell of uniform thickness, heated from below by a spatially uniform heat flux, and …

The magnetic fields of planets and stars are thought to play an important role in the fluid
motions responsible for their field generation, as magnetic energy is ultimately derived from …
