Inertial Forces Reproduce the Observed Variations of the Frequency of Geomagnetic Reversals

Albanian Journal of Natural and Technical Sciences
Understanding the geodynamo is a complex endeavor that heavily relies on advanced numerical modeling. Current magnetohydrodynamic (MHD) models, designed to replicate its behavior, operate within parameter regimes that are significantly removed from the ...

Magnetohydrodynamic Turbulence and the Geodynamo [PDF]

, 2016
Recent research results concerning forced, dissipative, rotating magnetohydrodynamic (MHD) turbulence will be discussed. In particular, we present new results from long-time Fourier method (periodic box) simulations in which forcing contains varying ...

Statistical Theory of the Ideal MHD Geodynamo [PDF]

, 2012
A statistical theory of geodynamo action is developed, using a mathematical model of the geodynamo as a rotating outer core containing an ideal (i.e., no dissipation), incompressible, turbulent, convecting magnetofluid.

Intermittence and peculiarities of a statistic characteristic of the geomagnetic field in geodynamo models

, 2020
© 2017, Pleiades Publishing, Ltd. The analysis of the statistical characteristics of the geomagnetic field generated in the numerical geodynamo models has shown that the distribution of the spherical harmonic coefficients in some cases is not Gaussian ...
