Internal heating in rapidly rotating convection is not a shortcut to geostrophic turbulence
Justin A. Nicoski, Tobias G. Oliver, Stefano Maffei +1
Convective turbulence in planets and stars is often driven by internal heating. This forcing mechanism has also been proposed as a means of accessing the diffusion-free scalings of…
Effects of global core-mantle boundary topography on outer-core convection and topographic torques
Tobias G. Oliver, Eric G. Blackman, John A. Tarduno +1
Topography at the core-mantle boundary (CMB) couples the outer core to the mantle and likely generates observable variations in the length of day (LOD) and the geomagnetic field…
Turbulence in Earth's core generates large topographic torques on the mantle
Tobias G. Oliver, Eric G. Blackman, John A. Tarduno +1
Seismic and geodynamic studies indicate that the boundary between the Earth's liquid outer core and solid mantle is not spherical, but is likely characterized by topography in the…
Small scale quasi-geostrophic convective turbulence at large Rayleigh number
Tobias G. Oliver, Adrienne S. Jacobi, Keith Julien +1
A numerical investigation of an asymptotically reduced model for quasi-geostrophic Rayleigh-Bénard convection is conducted in which the depth-averaged flows are numerically suppres…
