From left to right: ﹩{v}_{xy}^{\mathrm{total}}﹩, v_z, and compressibility (﹩{\boldsymbol{\nabla }}\cdot {\boldsymbol{v}}﹩) on the x–y plane for four time steps. The yellow and blue contours represent the fast magnetoacoustic and Alfvén parts, respectively, to distinguish ﹩{v}_{xy}^{\mathrm{total}}﹩ and v_z components of the velocity. The associated velocity amplitude range of the contour has been taken to be 30–35 km s⁻¹. The field of view (FOV) of the entire panel shown here is equivalent to the yellow dotted box shown in Figure 3 with dimensions [X,Y] = [(−70 Mm to −10 Mm), (60 Mm to 110 Mm)]. An animation of the above variables from 0 to 1025 s is available in the online version with a real-time duration of 10 s.
