Top: time averaged vertical profile of u_rms in the kinematic (dotted line) and saturated (solid line) stages for the Runs T04b. The dashed line shows the deviation from the average at a one of the peaks in the magnetic field amplitude. The three middle panels are butterfly diagrams of the angular velocity deviation, , for the Runs AR01, T04b and T04τ. The continuous white lines in these panels indicate the time evolution of B_rms normalized to its maximum value in the time interval. The bottom panels show time-averaged (solid black lines) and instantaneous (dashed red lines, referring to the white dash-dotted line in the bottom contour plot) values of U_y and ∂_zU_y.
