Scaling of the geomagnetic secular variation time scales
Yue-Kin Tsang, Chris A. Jones
The ratio of the Lowes spectrum and the secular variation spectrum measured at the Earth's surface provides a time scale as a function of spherical harmonic degree…
Jupiter's cloud-level variability triggered by torsional oscillations in the interior
Kumiko Hori, Chris A. Jones, Arrate Antuñano +2
Jupiter's weather layer exhibits long-term and quasi-periodic cycles of meteorological activity that can completely change the appearance of its belts and zones. There are cycles w…
Characterising Jupiter's dynamo radius using its magnetic energy spectrum
Yue-Kin Tsang, Chris A. Jones
Jupiter's magnetic field is generated by the convection of liquid metallic hydrogen in its interior. The transition from molecular hydrogen to metallic hydrogen as temperature and…
Anelastic torsional oscillations in Jupiter's metallic hydrogen region
Kumiko Hori, Robert J. Teed, Chris A Jones
We consider torsional Alfvén waves which may be excited in Jupiter's metallic hydrogen region. These axisymmetric zonal flow fluctuations have previously been examined for incompre…
Anelastic spherical dynamos with radially variable electrical conductivity
Wieland Dietrich, Chris. A. Jones
A series of numerical simulations of the dynamo process operating inside gas giant planets has been performed. We use an anelastic, fully nonlinear, three-dimensional, benchmarked…
The dynamics and excitation of torsional waves in geodynamo simulations
Robert J. Teed, Chris A. Jones, Steven M. Tobias
The predominant force balance in rapidly rotating planetary cores is between Coriolis, pressure, buoyancy and Lorentz forces. This magnetostrophic balance leads to a Taylor state w…
