Abstract
The three-component model of magnetic field fluctuations is applied to the analysis of the wave number spectra to study fluctuations in the solar wind, the foreshock, and the magnetosheath. The analysis exhibits a transition of the dominant fluctuation component from the solar wind to the magnetosheath, from the two-dimensional to the Alfvénic in the foreshock, and to the compressible component in the magnetosheath.
