Measurements of Cluster-2 with interrogation frequency 22.5 Hz for 2004-2010 years have been used for the analysis. The studies were conducted by statistical, fractal and spectral methods. During these investigations we have studied the changes of shape and parameters of probability density function for magnetic field fluctuations for periods of presence of the satellite in magneto-layer, solar plasma wind and in region of magnetopause. We have considered the evolution of change of maximum of probability density function, investigated structure functions of different orders (ESS-analysis); conducted fractal, spectral and wavelet analysis as characteristics of turbulent processes for different time scales. Results of the study were compared with available uniform and cascade turbulence models. It was determined that when crossing BS, not only increases the intensity fluctuations, but changes and their structure. We have found, that the highest intermittence is observed in the postshock region; fractal analysis is a more stable and localized in time compared to Fourier analysis and gives reliable results even in the analysis of scale that make up a significant part of the entire range of measurements. Fourier and wavelet analysis indicates the presence of cascade processes.
