• Starting from a recently developed turbulence-model of two components by C.-Y.

Tu and E. Marsch which describes pressure-balanced magnetohydrodynamic

fluctuations in the solar wind and which consists of five coupled nonlinear partial

differential equations for the calculation of turbulence-spectra for Alfvén-waves

and so-called convective structures, this work presents the development of a

numerical computer-code in order to enable researchers to carry out these

calculations in great detail for the solar wind. In accordance with results of

data-analysis in the solar wind radial trends such as the steepening of spectra

towards Kolmogorov-like spectra as well as a decay of structures convected with

the solar wind and outward propagating Alfvén-waves into convective structures

with the opposite sense of propagation and inward propagating Alfvén-waves in

the solar wind are found. The spectra of the inward propagating modes in the

solar wind show a characteristic concave bending along the frequency-axis

within the range of to Hz. If effects due to shear-flows are

dominating the turbulence develops towards energetic equipartition throughout

all scales in accordance to the observations. It is concluded that the trends

within the observations can be explained theoretically by a complex acting in

unison of transformations between convective structures and Alfvén-waves,

their scattering with each other as well as by nonlinear interactions, effects due

to shear-flows and the energetic coupling with the non-turbulent

plasma-background of the solar wind with it's special geometry.

• Numerical investigation of the magnetic reconnection between a magnetic cloud

and the solar wind magnetic field. When the magnetic cloud moves within the

oppositely directed, magnetic reconnection slowly dissolves the magnetic cloud. If

outer and inner magnetic field have a comparable strength, the cloud is dissolved

completely at Earth's orbit.

the shock that penetrates the slow CME steepens significantly. This shock creates

an environment that can effectively accelerate highly energetic particles.

• We present 2 1/2 D numerical MagnetoHydroDynamic (MHD) simulations of

coronal mass ejections (CMEs) in conjunction with plasma simulations of radio

emission from the CME-driven shocks. The CME-driven shock extends to an

almost spherical shape during the temporal evolution of the CME. Our plasma

simulations can reproduce the dynamic spectra of coronal type II radio bursts,

with the frequency drift rates corresponding to the shock speeds. We find further,

that the CME-driven shock is an effective radio emitter at metric wavelengths,

when the CME has reached a heliocentric distance of about two solar radii ().

We apply our simulation results to explain the radio images of type II bursts

obtained by radio heliographs, in particular to the bananashaped images of radio

sources associated with fast CMEs.

• CME-driven shocks are effective radio radiation generators and accelerators for

Solar Energetic Particles (SEPs). We present simulated 3 D time-dependent radio

maps of second order plasma radiation generated by CME-driven shocks. The

CME with its shock is simulated with the 3 D BATS-R-US CME model developed at

the University of Michigan. The radiation is simulated using a kinetic plasma

model that includes shock drift acceleration of electrons and stochastic growth

theory of Langmuir waves. We find that in a realistic 3 D environment of magnetic

field and solar wind outflow of the Sun the CME-driven shock shows a detailed

spatial structure of the density, which is responsible for the fine structure of type

II radio bursts. We also show realistic 3 D reconstructions of the magnetic cloud

field of the CME, which is accelerated outward by magnetic buoyancy forces in

the diverging magnetic field of the Sun. The CME-driven shock is reconstructed by

tomography using the maximum jump in the gradient of the entropy. In the

vicinity of the shock we determine the Alfven speed of the plasma. This speed

profile controls how steep the shock can grow and how stable the shock remains

while propagating away from the Sun. Only a steep shock can provide for an

effective particle acceleration.
