Turbulent convective length scale in planetary cores (NERC grant NE/M017893/1)

Data extracted from numerical simulations of rotating Boussinesq convection in spherical geometry and published in Guervilly, Cardin & Schaeffer (2019, https://doi.org/10.1038/s41586-019-1301-5). The simulations were run with Ekman numbers varying between 1e-6 and 1e-11, Rayleigh numbers between 6e7 and 5.25e13 and Prandtl numbers between 0.1 and 0.01. The data include: power spectra of the kinetic energy as a function of the azimuthal wavenumber; Rossby numbers and convective length scale; radial velocity in the equatorial plane for 4 selected simulations at varying Ekman number (Ek=1e-8 to 1e-11).

Statement

The numerical models solve the governing equations for Boussinesq rotating convection driven by homogeneous internal heating in a full sphere geometry. For the 3D simulations, we use the code XSHELLS (Schaeffer, Geochem. Geophys. Geosyst. 14, 751–758 (2013); Kaplan, Schaeffer, Vidal & Cardin, Phys. Rev. Lett. 119, 094501 (2017)). For the 2D simulations, we use a QG approximation for rapidly rotating spherical convection developed from the Busse annulus model. The full details of the methodology are available in Guervilly, Cardin & Schaeffer (2019, https://doi.org/10.1038/s41586-019-1301-5).
