Distributions of different variables in the zoomed lower atmosphere for the 2.5D run with B₀ = 5 G at time 3461.07 s, when a bunch of new spicules just start to appear at the altitude between Y = 0.5 and 2 Mm. The logarithmic temperature (lgT) (A), current density (J_z) (B), magnetic field in the Y-direction (B_y) (C), the negative divergence of velocity (− ∇ · V) (D), the acceleration along the Y-direction contributed by the pressure gradient (A_p) (E), and the acceleration along the Y-direction contributed by the Lorentz force (A_L) (F) are presented. The black thin solid line in panel (B) represents the position where the plasma β = 1.
