Total vertical Poynting flux of the advection term for the non-GOL (black) and GOL simulations (green) as a function of height. All values are averaged in time (over 1.5 minutes, snapshots = [360–370]) and in the horizontal direction. The vertical Poynting flux due to the ambipolar diffusion in the GOL simulation (red) is shown as a function of height. The dashed line is for horizontal motions (﹩{{P}_{z}}_{h}﹩), the dotted line is for vertical motions (﹩{{P}_{z}}_{z}﹩) and the solid line is the sum of both.
