Flux tube texture of the solar wind: Strands of the magnetic carpet at 1 AU?

An extremely graceful pastel cartoon, depicting what must be a plausible understanding of the magnetic field in the solar wind. It contains flux tubes, more or less defined by solar structures and persisting because of the inefficiency of magnetic reconnection in this essentially collisionless medium. The intertwining of these flux tube as they meander through the heliosphere may enhance their eventual loss of identity, but in the meanwhile they must play a major role in the heliospheric propagation of particles (e.g., SEPs) and waves. The paper notes that the size scales of these flux tubes, though observed in situ far from the Sun, correspond to granule scales at the surface.

      If this represents the structure of the solar wind, can it really be thought of as "turbulent" in any truly random sense?
