| Zusammenfassung |
| Over the past few decades scientists have shown growing interest in space
plasma complexity and in understanding the turbulence in magnetospheric and
interplanetary media. At the beginning of the 1980s, Yu. L. Klimontovich
introduced a criterion, named S-Theorem, to evaluate the degree of order in
far-from-equilibrium open systems, which applied to hydrodynamic turbulence
showed that turbulence flows were more organized than laminar ones. Using the
same theorem we have evaluated the variation of the degree of
self-organization in both Alfvénic and non-Alfvénic turbulent
fluctuations with the radial evolution during a long time interval
characterized by a slow solar wind. This analysis seems to show that the
radial evolution of turbulent fluctuations is accompanied by a decrease in
the degree of order, suggesting that, in the case of slow solar wind, the
turbulence decays with radial distance. |
