Pink Bar (IMAGE)
Caption
In the top bar, the ceiling of the tunnel is flat; in the middle bar, the ceiling is halfway down; the bottom bar shows turbulence when the ceiling is all the way down. The white portion is the fastest and quietest area of turbulence. The internal layer is shown as the deepest pink color close to the wall.
