I am curious what specific gas model theories would be useful in explaining the consistent "patterns" we see in solar "running difference" and doppler images such as these:

This video spans more than an hour yet the "patterns" remain relatively fixed compared to the plasma activity at the surface of the photosphere where structures come and go every 8 minutes or so. Why aren't these structures showing any signs of differential rotation, or the boiling patterns that are typically seen in the plasma of the photosphere?
Here is some background information and the supporting SOHO Doppler image that was put together by Alexander Kosovichev from Stanford:

I'm specifically curious about the angular structure we see under the wave to the left of the center of the wave. Why is that structure more "rigid" than the plasma that carries the wave? How is that structure holding it's angular shape as the wave passes over it?
