| Zusammenfassung |
| Magnetospheric cusps are high-latitude regions characterized by a highly turbulent
plasma, playing a special role in the solar wind-magnetosphere interaction. Here, using POLAR satellite
magnetic field vector measurements we investigate the anisotropic scaling features of the magnetic field
fluctuations in the northern cusp region. Our results seem to support the hypothesis of a 2D-MHD
turbulent scenario which is consequence of a strong background magnetic field. The observed turbulent
fluctuations reveal a high degree of complexity, which might be due to the interplay of many competing
scales. A discussion of our findings in connection with the complex scenario proposed by Chang et al. (2004)
is provided. |
