Dynamics of Slow Solar Wind Emerging from an Equatorial Coronal Hole
We present a three-dimensional reduced magnetohydrodynamics model to depict turbulence induced by Alfvén waves within the slow solar wind originating from an open magnetic field positioned in a coronal hole near the solar equator.

Radial evolution of cross helicity at low and high latitudes in the solar wind
We employ a turbulence transport theory to the radial evolution of the solar wind at both low and high latitudes. The theory includes cross helicity, magnetohydrodynamic (MHD) turbulence, and driving by shear and pickup ions. The radial decrease of cross

On the Formation of Super-Alfvénic Flows Downstream of Collisionless Shocks
Super-Alfvénic jets, with kinetic energy densities significantly exceeding that of the solar wind, are commonly generated downstream of Earth's bow shock under both high- and low-beta plasma conditions. In this study, we present theoretical evidence that

In this thesis I study a variety of two-dimensional turbulent systems using a mixed analytical, phenomenological and numerical approach. The systems under consideration are governed by the two-dimensional Navier-Stokes (2DNS), surface quasigeostrophic

Intermittent character of interplanetary magnetic field fluctuations
Interplanetary magnetic field magnitude fluctuations are notoriously more intermittent than velocity fluctuations in both fast and slow wind. This behavior has been interpreted in terms of the anomalous scaling observed in passive scalars in fully ...

Spectral Anisotropy at Ion Scales in the Solar Wind Upstream of the Martian Bow Shock
The spectral anisotropy of magnetic field fluctuations at ion scales in the solar wind upstream of the Martian bow shock remains poorly understood. In the solar wind near the Earth’s orbit, such anisotropy is known to be modulated by ion-scale waves ...

A Complete Theory for Nondiffusive Field Line Random Walk in Magnetic Turbulence
Previous analytical and numerical investigations of the stochastic properties of field lines in magnetic turbulence have been based on determining the running field-line diffusion coefficient.

Turbulent accumulation of interplanetary magnetic fluxes at the Venus ionopause
The accumulation of interplanetary magnetic fluxes around the Venus ionopause is examined in the light of the PVO magnetometer and plasma wave measurements. It is argued that convective electric currents within the ionosphere are not sufficient to account for the observed geometry of the magnetic profiles. It is suggested that turbulent flow conditions
