Connections between nonrotating, slowly rotating, and rapidly rotating turbulent convection transport scalings

JM Aurnou, S Horn, K Julien - Physical Review Research, 2020 - APS
In this paper, we investigate and develop scaling laws as a function of external
nondimensional control parameters for heat and momentum transport for nonrotating, slowly …

Longitudinal structure of Earth's magnetic field controlled by lower mantle heat flow

JE Mound, CJ Davies - Nature Geoscience, 2023 - nature.com
Thermal interactions between Earth's core and mantle provide the power that maintains the
geomagnetic field. However, the effect of these interactions and, in particular, the …
