The distributions of plasma parameters at different altitudes. Panel (A) shows the distributions of initial temperature, density​​, and pressure along the Y-direction, and they are normalized by using the reference values (T₀ = 6530 K, rho₀ = 2.734⁻⁴ kg m⁻³ and P₀ = 11820 N m⁻² ) at the bottom of the photosphere. The evolutions of temperature and density at different altitudes are presented in panels (B) and (D), and these values are the averaged ones in the X-direction.
