- Abstract:
- I propose to build a simple numerical model to test a mechanism for the excitation of torsional oscillations in the Earth's core. It comprises a mean differential rotation acting on a non-axisymmetric magnetic field. I also plan to investigate the characteristics of geomagnetic jerks by determining the attributes of the magnetic field and flow that lead to them. I also plan to investigate a possible link between archaeomagentic field variations and the long term fluctuations in the length of day, which both have periods of about 1500 years. The results are likely to lead to useful constraints for the geodynamo at a thousand year timescale.
