A better knowledge of the statistical features of reconnection and bursty bulk
flow associated turbulence is essential for the understanding of multi-scale
redistribution of energy in the Earth's plasma sheet. Statistical analysis
of multi-scale properties of turbulence facilitates to understand the
interaction of the plasma flow with the dipolar magnetic field and to
recognize the remote or nearby temporal and spatial characteristics of
reconnection. The main emphasis of this presentation is on studying
the specific statistical features of reconnection and plasma flow
associated magnetic fluctuations. The transiency of driving and the
associated non-stationarity of multi-scale fluctuations makes the estimation
of statistical features difficult. Additional complexity is introduced by
the presence of waves, boundaries or/and large-scale gradients which
induce anisotropic fluctuations and increase intermittency. Nevertheless,
the scaling ranges associated with MHD turbulent cascade, Hall
-MHD and large-scale fluctuations can be identified.
