Dear "loops" friends,
You might be interested in the paper that Spiro and I just published concerning the role of turbulence in forming the current sheets that spawn nanoflares in the magnetically closed corona:

We argue that the sheets form primarily from other processes, unrelated to turbulence. Localized temporary bursts of turbulence may nonetheless be generated when the sheets reconnect.
Abstract: We argue that the magnetically closed corona evolves primarily quasi-statically, punctuated by many localized bursts of activity associated with magnetic reconnection at a myriad of small current sheets. The sheets form by various processes that do not involve a traditional turbulent cascade whereby energy flows losslessly through a continuum of spatial scales starting from the large scale of the photospheric driving. If such an inertial range is a defining characteristic of turbulence, then the magnetically closed corona is not a turbulent system. It nonetheless has a complex structure that bears no direct relationship to the pattern of driving.
Cheers, Jim
