Vertical cuts of the sonic Mach number taken at z = 0 in the simulations of the SSD run with b = 10⁻⁶ on the 192 × 96 × 192 grid. Each panel is taken at a different moment in time, which is given in the title. As the SSD approaches the saturated regime, the small-scale structures in the velocity field are damped by the Lorentz force, and vertical motions mainly happen in the form of large-scale flows.
