Electrical conductivity of the lowermost mantle explains absorption of core torsional waves at the equator
Abstract Torsional Alfvén waves propagating in the Earth's core have been inferred by inversion techniques applied to geomagnetic models. They appear to propagate across the core but vanish at the equator, exchanging angular momentum between core and mantle. Assuming axial symmetry, we find tha...
