Background atmosphere taken at Y = 7 Mm (from the Y-origin at the spot center). The top and bottom left panels show the temperature and magnetic field variations of the background atmospheric conditions, respectively. The white contours with arrows show the in-plane projections of the background magnetic field lines, and the near-horizontal curve across the domain is the equipartition layer where c_s/v_A = 1. The top right panel shows the plasma properties as a function of height at the center of the domain (corresponding to the vertical dashed line in the left panels). Similarly, the bottom right panel shows the variation of sound and Alfvén speeds as a function of height at the center of the domain.
