Similar to Fig. 6, but now for the vertical component of momentum. The panels show the vertical (horizontal) transport of vertical momentum, represented by the solid (dashed) red curves. The black curve indicates the contribution of the vertical pressure gradient, the blue curve the contribution of gravity, and the green curve the contribution of the Lorentz force. The panels from top left to bottom right are sorted from smaller to larger wavenumber. Top left: results at wavenumber k = 7 Mm⁻¹ (wavelength 900 km). Top right: wavenumber k = 11.4 Mm⁻¹ (wavelength 550 km). Bottom left: wavenumber k = 15.7 Mm⁻¹ (wavelength 400 km). Bottom right: wavenumber k = 20 Mm⁻¹ (wavelength 312 km).
