Three-dimensional spatial structures of solar wind turbulence from 10 000-km to 100-km scales
Using the four Cluster spacecraft, we have determined the three-dimensional wave-vector spectra of fluctuating magnetic fields in the solar wind. Three different solar wind intervals of Cluster data are investigated for this purpose, representing three different spatial scales: 10 000 km, 1000 km, and 100 km. The spectra are determined using the wave telescope technique (k-filtering technique) ...
متن کاملSpatial correlation of solar-wind turbulence from two-point measurements.
Interplanetary turbulence, the best studied case of low frequency plasma turbulence, is the only directly quantified instance of astrophysical turbulence. Here, magnetic field correlation analysis, using for the first time only proper two-point, single time measurements, provides a key step in unraveling the space-time structure of interplanetary turbulence. Simultaneous magnetic field data fro...
متن کاملAnisotropy of solar wind turbulence between ion and electron scales.
The anisotropy of turbulence in the fast solar wind, between the ion and electron gyroscales, is directly observed using a multispacecraft analysis technique. Second order structure functions are calculated at different angles to the local magnetic field, for magnetic fluctuations both perpendicular and parallel to the mean field. In both components, the structure function value at large angles...
متن کاملOrigin of Perpendicular Scales in Solar Wind Turbulence
Results of a study of dispersive Alfvén modes propagating outward from the Sun in streaming inhomogeneous plasma are presented for the inner heliosphere (1 AU) region. The results clearly show that a combination of nonlinear wave–particle and wave–wave interactions of outward-only Alfvén modes initially propagating along the local background magnetic field is perfectly capable of explaining th...
متن کاملFuture Studies and KM
Futures studies is a value knowledge and has a two-way communication with the worldview, ideology and culture of nations. Humanities is one of the factors that influence the field of futures studies. Hence the human sciences itself could be the subject of future studies. In this study, we have tried to discuss the role of future studies in knowledge management in the field of humanities. Theref...
