Simulation 2, a non-kinematic α²Ω dynamo exhibiting parity modulation. (A) Normalized magnetic energy in black, the shear proxy (Ψ) integrated in the meridional plane in red, and the parity in light blue. (B) Toroidal magnetic field in a time-latitude diagram extracted at 0.85R and (C) the angular velocity fluctuation (Ω′(r, θ, t)/Ω(r, θ)) in the same configuration. The meridional cuts of the toroidal field B and angular velocity perturbation Ω′ plotted at right of the time-latitude diagrams are extracted at t/τ = 2.7, as indicated by the dash-dotted line segments on the corresponding time-latitude diagrams.
