By looking at the corresponding multiscale features, we observe a break in the average attractor dimension occurring at the crossover between the inertial and the kinetic/dissipative regime. Our analysis suggests that large-scale transitions are induced by small-scale dynamics through an inverse cascade mechanism driven by local correlations, while electron contributions (if any) are hidden by instrumental noise.STAMPAen10.3847/2041-8213/ac0148https://iopscience.iop.org/article/10.3847/2041-8213/ac01482021ApJ...914L...6AFIS/05 - ASTRONOMIA E ASTROFISICA
