| Zusammenfassung |
| Secondary and tertiary flow patterns seen in experiments simulating flow in
the Earth's liquid core induced by luni-solar precession of the solid mantle
(Vanyo et al., 1995) hint at the development of non-axisymmetric columnar
periodic structures. A simple interpretation of the structure formation is
presented in a hydrodynamic approach. It is suggested that if similar flow
patterns can occur in the Earth's liquid core enclosed into precessing and
rotating mantle then kinematic of the flows may be regarded as a possible
geodynamo mechanism for early Earth's history (before the solid core
formation). |
