Profiles of B_eq and B_z at z = 0 (i.e., the surface of the turbulent region), for Run B1 with Co = 0.0015, θ = 0 at t/τ_td = 1 and along y = 0 (black line). The red solid line gives the Fourier-filtered profiles of B_z. The dotted orange line gives the values of B_eq through the magnetic structure based on the local turbulent pressure and the solid orange lines denotes its Fourier-filtered value. The blue line represents the value of B_eq based on the volume-averaged velocity, but the local density, which does not show the local suppression of u_rmsAll values have been normalized by the volume-averaged value of B_eq.
