Abstract
The Earth’s magnetic field has undergone temporal and spatial variations including polarity reversals. Paleomagnetic and historical magnetic field measurements suggest persistent distinct patterns of variation of the geomagnetic field taking place in different regions of the Earth. At least on the millennia time scale these patterns may be explained by the thermal influence of Earth’s mantle on the geodynamo. Whether this influence can already be discerned on the century time scale is still debated. Although, the Earth’s interior is inaccessible for direct observations, the effects of such processes at the top of the core and below are well observed at the Earth’s surface. Several observables of these processes are used to infer the dynamical regime of Earth’s outer core and its interaction with its vicinity.
