Vertical profiles of V_y (left) and Β_ν (right) in the simulations of the SSD, averaged over 20 < t/τ_conv < 40. Different colors represent different grid resolutions, while different line styles are used for representing different values of b. The vertical velocity is rescaled by b^2/3 to remove the dependence of the energy injection rate, while Β_y is rescaled by the corresponding equipartition value, .
