Reflections on the Geodynamo by Prof Peter Davidson, University of Cambridge, Engineering Department

Abstract

Numerical simulations of the geodynamo are, perhaps, finally beginning to approach a dynamically relevant regime. It seems timely, therefore, to compare the results of those simulations with the various conceptual cartoons of the geodynamo that have been developed over the decades. One such cartoon is presented here, based in part on helical wave dispersion within the Earth’s core. This cartoon is far from the standard model, but nevertheless seems consistent with the evidence of the numerical simulations. Of course, understanding the numerical simulations is not at all the same as understanding the geodynamo, but perhaps it is a start.
