| Summary: | Statistics associated with the fluctuations in solar wind parameters show a
remarkable dependence on the solar activity phase.
In particular, we focus our attention on the waiting-time statistics
governing the MHD fluctuations of the z-component of the interplanetary
magnetic field, which are important within the framework of the Sun-Earth connections, and
briefly discuss the preliminary results.
Data from several spacecrafts, covering different phases of the solar cycle and
different radial distances, are used. We found that propagating Alfvénic
fluctuations and convected structures strongly influence the
statistics which vary from quasi-Poissonian to power law. |
