| Zusammenfassung |
| Incompressible and isotropic magnetohydrodynamic turbulence in plasmas can be described by an exact relation for the energy flux through the scales. This Yaglom-like scaling law has been recently observed in the fast solar wind above the solar poles, where the turbulence is in an Alfvénic state, as well as in the ecliptic by separating fast (Alfvénic) and slow (non Alfvénic) stream. The results provides insights on the nature of solar wind turbulence, on its implications for energy transfer and heating, and on the role of Alfvénicity in the formation of the
magnetohydrodynamic turbulent cascade. |
