REVERSALS IN THE SIX-JET GEODYNAMO MODEL
Journal Title: Вестник КРАУНЦ. Физико-математические науки - Year 2016, Vol 3, Issue
Abstract
We describe a large-scale geodynamo model based on hypothesis about 6-jet convection in the Earth’s core. This hypothesis suggests indirect data of inhomogeneities in the density of the Earth’s core. The convection pattern is associated with a spherical harmonic Y24 which defines the basic poloidal component of velocity. The model takes into account the feedback effect of the magnetic field on convection. It was ascertained that the model contains stable regimes of field generation with reversals. The velocity of convection and the dipole component of the magnetic field are similar to the observed ones.
