| Zusammenfassung |
| It is well known that the structure of
magnetic field lines in solar wind can be influenced by the presence of
the magnetohydrodynamic turbulence. We have developed a Monte Carlo
simulation which traces the magnetic field lines in the heliosphere,
including the effects of magnetic turbulence. These effects are modelled
by random operators which are proportional to the square root of the
magnetic field line diffusion coefficient. The modelling of the random
terms is explained, in detail, in the case of numerical integration by
discrete steps. Furthermore, a proper evaluation of the diffusion
coefficient is obtained by a numerical simulation of transport in
anisotropic magnetic turbulence. The scaling of the fluctuation level and
of the correlation lengths with the distance from the Sun are also taken
into account. As a consequence, plasma transport across the average
magnetic field direction is obtained. An application to the propagation of
energetic particles from corotating interacting regions to high
heliographic latitudes is considered. |
