Caption: Figure 7.

Counter-QFP-produced density (Δρ/ρ0; left) and velocity (v; right) perturbations in the xz plane at y = 0, overlaid with magnetic field lines and velocity direction arrows (right panels only). From top to bottom are three simulation cases. (a) and (b): Case 1 at t = 119τA; (c) and (d): Case 2 at t = 98.4τA; (e) and (f): Case 3 at t = 98.3τA. The dashed lines mark the locations of the space–time cuts of the model results in Figures 9(d)–(f) below. The cyan arrows mark some of the compressions associated with the trapped slow-mode wave. An animation of panel (e) is available online.
