Comparison of the WMI (left) and velocity (right) components at two different times for the weak field with radial driving simulation. The top panels show the parallel components ν_∥ (top left) and u_∥/c₀ (top right) at t = 58.5 s. The middle panels show the parallel components ν_∥ (middle left) and u_∥/c₀ (middle right) at t = 81.9 s. The bottom panels show the perpendicular components ν_⊥ (bottom left) and u_⊥/c₀ (bottom right) also at t = 81/.9 s. For each row, lines of the respective ν_* = ±0.05 are overplotted to make comparison between the figures easier. Red, black (non-contour) and white lines are as in Figure 2.
