Radial and vertical flow velocities at three depth levels for the snapshot at t = 46.4 hr. The top row shows radial flow velocity and the bottom row shows vertical flow velocity. Left to right the depth levels z = −11.5 Mm, z = −3.3 Mm, and z = −1.3 Mm. The ring-like arrangement of convection cells is present at all depth levels, and the diameter of the region in which the presence of the sunspot modifies the convection pattern is increasing with depth as the intrinsic scale of convection is increasing with pressure scale height.
