  • Seismic waves sampling the top 100 km of the Earth's inner core have revealed that the eastern hemisphere is seismically faster, more isotropic and more attenuating than the western hemisphere. It is now shown that a single model of thermo-chemical convection and dynamo action can account for all these effects by producing a large-scale, long-term outer core flow that couples the heterogeneity of the inner core with that of the lower mantle.
