Improved laboratory and computational models for thermal core–mantle interaction
The Earth's magnetic field is generated by thermochemical convection within its fluid outer core. The near-stationary high-latitude magnetic flux concentrations in the present day field indicate that convective ... -
An investigation into the axial dipole field and mantle-induced heterogeneity in Earth
The Earth’s axial dipole field is generated by dynamo action in the planet’s outer core. It is understood from observations that the convection in the outer core is influenced by the lateral heterogeneity in the overlying ... -
An investigation of the role of buoyancy in magnetic polarity transitions in rapidly rotating dynamos
The dynamo operating within the Earth’s outer core generates a predominantly north-south dipolar magnetic field. Occasionally, the magnetic dipole axis flips its orientation and retains its approximate alignment with the ... -
MHD Waves Driven by Small-scale Motion and Implications for the Earth's Core
(2018-05-22)Rotating convection in the Earth's core produces columnar vortices of radius ~10 km or less near the inner core boundary. Small-scale motions in the core can travel as Alfvén waves in the face of Ohmic diffusion, provided ...
