Scientific paper

The solar wind is the most studied laboratory of space plasma turbulence. Here, at MHD scales, the Kolmogorov's power law f-5/3 is observed for Alfvénic fluctuations, which dominate the turbulent spectrum. Above the spectral break in the vicinity of the ion cyclotron frequency fci, the spectrum becomes steeper, ~ f-3, and the level of compressible fluctuations raises. This range is usually called dissipation range of solar wind turbulence. Using Cluster Search Coil magnetometer data, we show that the statistical properties of the fluctuations above the spectral break (at f>fci) are inherent to an inertial and not to the dissipative range. The analysis of Cluster Spectrum Analyser data (spectra from 8~Hz up to 4~kHz) is performed in order to possibly establish the starting scale of the dissipation range. The Earth's magnetosheath is another example of magnetic turbulence in space plasmas. Here, the Kolmogorov power law at f
