Overview of the global models. All simulations use Pm = 16 and insulating magnetic boundary conditions. The (n_r, n_θ, n_ϕ) = (257, 512, 1024) resolution is called “Medium” and the (n_r, n_θ, n_ϕ) = (385, 768, 1536) resolution is called “High”. Ra corresponds to the Rayleigh number linked to the Brunt-Väisälä frequency (see Eq. 21), Pr to the thermal Prandtl number, B_o to the initial magnetic field strength at the outer boundary. Magnetic field and dipole field strengths are time and space averaged. P_sim corresponds to the estimated period of the mean-field dynamo patterns at r = 0.92 r_o, k_z to the vertical wavenumber and qΩ to the value in the turbulent region (at r = 0.92 r_o). k_z, qΩ and the alpha component α_ϕϕ are used to compute the theoretical αΩ period P_αΩ.
