| Zusammenfassung |
| The magnetosheath is characterized by a variety of low-frequency
fluctuations from different sources. In our previous studies, we
analyzed magnetic field fluctuations of multipoint Cluster spacecraft
observations near dusk/dawn meridian and we have found that the
correlation length of these fluctuations depends on the solar wind
speed, on a correlation between IMF and magnetosheath magnetic field
fluctuations, and on the amplitude of fluctuations. To determine the
correlation length in different magnetosheath places and degree of
penetration of solar wind fluctuations into the magnetosheath, we use
different solar wind monitors and different separations between the
magnetosheath spacecraft (Cluster, Themis) and correlation and wavelet
techniques. We discuss the influence of foreshock fluctuations on the
correlation between the magnetosheath spacecraft. |
