Stochastic model of 6-jet kinematic dynamo [PDF]
E3S Web of Conferences, 2019 The low-moded stochastic model of kinematic geodynamo is studied. The model is based on the indirect data about the large-scale structure of convection.

The "Yin-Yang Grid": An Overset Grid in Spherical Geometry
, 2004 A new kind of overset grid, named Yin-Yang grid, for spherical geometry is proposed. The Yin-Yang grid is composed of two identical component grids that are combined in a complemental way to cover a spherical surface with partial overlap on their ...

Testing the Accuracy of Paleointensity Estimates Using Experimental Pottery Assemblages
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.Abstract Paleointensity estimates from archaeological pottery represent a key source of information on Holocene variations in geomagnetic field intensity. Yet, pottery rarely exhibits ideal single‐domain behavior that fully satisfies the theoretical assumptions underlying absolute paleointensity methods.

Kinematic-gravity model of geodynamo
Геофизический журнал, 2013 Based on the results of solving the inverse problem of magnetometry and analysis of some known models of the Earth magnetic field generation a model is proposed in which the current producing magnetic field is the vortex motion of positively charged ...

Three-dimensional solutions for the geostrophic flow in the Earth's core [PDF]
, 2018 In his seminal work, Taylor (1963) argued that the geophysically relevant limit for dynamo action within the outer core is one of negligibly small inertia and viscosity in the magnetohydrodynamic equations. Within this limit, he showed the existence of a

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.Abstract Mercury's tectonic record is dominated by shortening landforms, including lobate scarps, high‐relief ridges and wrinkle ridges. Previous analyses of these structures have used displacement–length ratios to constrain the planet's global contraction to a range of either no more than 2 km or up to 7 km.

Prandtl-number dependence of convection-driven dynamos in rotating spherical fluid shells [PDF]
, 2005 The value of the Prandtl number P exerts a strong influence on convection-driven dynamos in rotating spherical shells filled with electrically conducting fluids.

Motional Induction in Ganymede's Ocean
Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.Abstract We investigate the magnetic signature of oceanic circulation in Ganymede's subsurface ocean using kinematic induction modeling. Our approach couples zonal jet flows from rotating thermal convection simulations with magnetic field models incorporating Ganymede's internal dynamo and external contributions from Jupiter.

Scaling of Latitude‐Dependent Heat Transport in Geostrophic Convection
Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.Abstract Latitudinal variations in heat transport shape the thermal and magnetic evolution of rapidly rotating planets, stars, and icy moons. Although global simulations have revealed strong equatorial–polar contrasts, a predictive scaling theory has been lacking.
