The flow in the Earth's interior caused by the mutual rotation of the mantle and the solid core.
Abstract
Differences in the angular velocities of the mantle and the solid core are found to lead to large-scale flow including differential rotation and meridional circulation in the density-stratified liquid outer core. The steady-state differential of angular velocities is sustained by the balance of moments of external (tidal) forces and internal viscous and magnetic friction.
