Paleomagnetic signatures of core-mantle interactions inferred from top-heavy thermochemical geodynamo simulations
Souvik Naskar, Jonathan E. Mound, Christopher J. Davies +3
The time-averaged geomagnetic field provides crucial insights into deep Earth dynamics and thermal core-mantle interactions. Paleomagnetic observations and numerical dynamo simulat…
Thermochemical models of outer core convection with heterogeneous core-mantle boundary heat flux
Souvik Naskar, Jonathan E. Mound, Christopher J. Davies +1
Convection in Earth's outer core is driven by the release of heat and light elements at the inner core boundary. A key question is whether these buoyancy sources drive convection t…
Geomagnetic signatures of the slurry F-layer inferred from dynamo simulations
Ludovic Huguet, Thomas Frasson, Souvik Naskar +5
Seismic observations indicate that the lowermost portion of Earth's liquid core is density stratified. The existence of this so-called F-layer challenges classical theories of core…
Accessing the dipole-multipole transition in rapidly rotating spherical shell dynamos
Andrew T. Clarke, Christopher J. Davies, Souvik Naskar +1
Polarity reversals are a key feature of Earth's magnetic field, yet the processes governing them are still poorly understood. Dipole reversals have been found in many numerical dyn…
Force balances in spherical shell rotating convection
S. Naskar, C. J. Davies, J. E. Mound +1
Significant progress has been made in understanding planetary core dynamics using numerical models of rotating convection (RC) in spherical shell geometry. However, the behaviour o…
