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

The interplanetary induced electric field e=v x b 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.
