太阳风中感生电场的单点统计和不稳定性

One-point statistics and intermittency of induced electric field in the solar wind

Luca Sorriso-Valvo, Vincenzo Carbone, Roberto Bruno

摘要:

利用太阳风时间序列研究了行星际感应电场e=vxb。从数据中测量了电场分量的概率分布函数(PDF),并讨论了它们的非高斯性。此外,我们第一次表明,电场湍流的特点是不连续性。这一点是通过研究,像往常一样,缩放的PDF字段增量,它允许定量表征的不稳定性。

英文摘要:

The interplanetary induced electric field e=vxb is studied, using solar wind time series. The probability distribution functions (PDFs) of the electric field components are measured from the data and their non-gaussianity is discussed. Moreover, for the first time we show that the electric field turbulence is characterized by intermittency. This point is addressed by studying, as usual, the scaling of the PDFs of field increments, which allows a quantitative characterization of intermittency.
