| Abstract: | The distribution of the shocks in the heliosphere and their characteristic variations are investigated using Ulysses observations. The jumps in solar wind velocity, IMF magnitude, and proton density across the shocks and discontinuities are
evaluated and used to characterize them. The distribution of these discontinuities with respect to heliolatitude ± 80° and
with radial distance 1 to 5 AU are analyzed during solar minimum and solar maximum to understand their global behavior. It
is noticed that the jumps in solar wind parameters associated with shocks and discontinuities are more prominent during the
second orbit of Ulysses, which coincided with the maximum phase of solar activity. |
