Snapshots of spatial profiles of the total velocity Vi (color map) expressed in the units of km s−1, and velocity vectors (arrows) at t = 0 s (a, launch of Gaussian pulse as mentioned in Eq. (19)), t = 60 s (b), t = 135 s (c), and t = 160 s (d) for initial B = [0, 10, 0] Gs. This configuration will lead to the generation of MAWs. The spatial profile of Vi (color map) here represents the propagation of the MAWs in the chromosphere (0.5 ≤ y ≤ 2 Mm) and in higher layers of the solar atmosphere. The black arrows indicate the direction of the plasma flow.
