| Zusammenfassung |
| A short review of recent observations of
solar wind fluctuations in the magnetohydrodynamic (MHD) range of scales is
presented. In recent years, the use of high time-resolution data on an extended
interval of heliocentric distance has allowed significant advances in our
knowledge of MHD fluctuations. We first focus on the origin and evolution of the
Alfvénic-type fluctuations. The role of interplanetary sources and the
influence of interactions with structures convected by the solar wind are
examined. Then compressive fluctuations are investigated, with special attention
being given to their nature and origin. Observations are discussed in the light
of recent theories and models. Finally, predictions for MHD turbulence in polar
regions of the heliosphere are highlighted. |
