Physical quantities of the considered 1D atmospheric model extracted from the 3D MHD Bifrost simulation en024048_hion (snapshot 385, column 120 × 120). Upper panel: strength (blue solid line), inclination (gray dashed line), and azimuth (light-blue dashed-dotted line) of the magnetic field as a function of height. Lower panel: vertical component of bulk velocity (green solid line) and temperature (red solid line) as a function of height. We adopt the convention that the velocity is positive if pointing outward in the atmosphere and negative if pointing inward. For clarity, the horizontal green dotted line indicates zero velocity.
