Sažetak
The main physical processes, describing the transport of charged particles in the inner helio- sphere, are summerized by Parker’s transport equation. To investigate the parameter space, many different particle populations such as in this case electrons accelerated in Jupiter’s mag- netosphere have been used for several decades. However, the variety of different parameters is still a challenge for systematic investigation such as determining the diffusion coefficients, affecting the propagation of these particles. Utilizing a GPU-accelerated algorithm to solve Parker’s transport equation by means of stochastic differential equations (SDEs) such goals become reachable. In order to expand the possibilities of this method we will present an parameterized approach to include the influence of Coronal Mass Ejections (CMEs) on the diffusive and convective transport processes. Therefor the variation of the solar wind speed due to the ejecta is utilized to derive the magnetic compression and rarefaction regions and their influence on the diffusion parameters
