| Zusammenfassung |
| In this work we consider the important problem of selection of slow and fast solar wind data
measured in-situ by the Ulysses spacecraft during two solar minima (1995-1997, 2007-2008)
and solar maximum (1999-2001). To recognise different types of solar wind we use a set of
following parameters: radial velocity, proton density, proton temperature, the distribution of
charge states of oxygen ions, and compressibility of magnetic field. We present how this idea
of the data selection works on Ulysses data. In the next step we consider the chosen
intervals for fast and slow solar wind and perform statistical analysis of the fluctuating
magnetic field components. In particular, we check the possibility of identification of
inertial range by considering the scale dependence of the third and fourth orders
scaling exponents of structure function. We try to verify the size of inertial range
depending on the heliographic latitudes, heliocentric distance and phase of the solar
cycle.
