Titolo: | Small-scale Induced Large-scale Transitions in Solar Wind Magnetic Field | Autori: | ALBERTI, TOMMASO Faranda, Davide Donner, Reik V. Caby, Theophile CARBONE, VINCENZO CONSOLINI, Giuseppe Dubrulle, Berengere Vaienti, Sandro |
Data pubblicazione: | 2021 | Rivista: | THE ASTROPHYSICAL JOURNAL LETTERS | Numero: | 914 | Fascicolo: | 1 | Da pagina:: | L6 | Abstract: | We investigate the role of small-scale dynamics in inducing large-scale transitions in the solar wind magnetic field by means of dynamical system metrics based on instantaneous fractal dimensions. 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. | URI: | http://hdl.handle.net/20.500.12386/32166 | URL: | https://iopscience.iop.org/article/10.3847/2041-8213/ac0148 | ISSN: | 2041-8205 | DOI: | 10.3847/2041-8213/ac0148 | Bibcode ADS: | 2021ApJ...914L...6A | Fulltext: | open |
