Numerical Simulations of Models for the Geodynamo
Project runtime:
2000-2004
Funding:
DFG Bu589/10-1 in the priority programme 'Geomagnetic Variations: Spatio-Temporal Structure, Processes, and Effects on System Earth'
Project description:
The understanding of convection driven dynamos in rotating spherical shells has progressed rapidly in the past decade through the use of large scale numerical simulations such that more specific models can now be considered for the elucidations of properties of the geodynamo operating in the liquid core of the Earth. It is planned to investigate the influence of lateral inhomogeneities at the core-mantle boundary on the generation of magnetic fields and to analyse the processes of execusions and reversals in a systematic manner. In the numerical simulations the use of hyperdiffusivities will be avoided since they appear to introduce unrealistic properties of the dynamo process.
