Role of driving scales in a model of coronal heating
Abstract : Models of coronal heating based on the dissipation of small‐scale current sheets generally assume energy injection at large scales by photospheric motions. However due to the nature of these motions, excitation mechanisms may occur on a wide range of scales. We study the role of the dominant scales of energy injection in the framework of the lattice model introduced in [1]. In particular it is shown that as the weight of large scales increases, the probability densities of dissipated energy and of waiting times between heating events develops fatter tails tending toward power‐laws.
