Solar and Interplanetary Turbulence: Lagrangian Coherent Structures
, 2020 <p>The dynamics of solar and interplanetary plasmas is governed by coherent structures such as current sheets and magnetic flux ropes which are responsible for the genesis of intermittent turbulence via magnetic reconnections in solar supergranular junctions, solar coronal loops, the shock-sheath region of an interplanetary ...

Radial evolution of cross helicity in high-latitude solar wind [PDF]
, 2005 We employ a turbulence transport theory to explain the high-latitude radial evolution of cross helicity, or Alfvénicity, observed by the Ulysses spacecraft.

An analytical, phenomenological and numerical study of geophysical and magnetohydrodynamic turbulence in two dimensions [PDF]
, 2013 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

Turbulence development behind the bow shock during disturbed and undisturbed solar wind
Solar-Terrestrial PhysicsMagnetosheath is a transition layer between the solar wind and the magnetosphere and may contribute to the geoeffectiveness of various large-scale interplanetary phenomena.

Quantifying scaling in the velocity field of the anisotropic turbulent solar wind [PDF]
, 2007 Solar wind turbulence is dominated by Alfvénic fluctuations with power spectral exponents that somewhat surprisingly evolve toward the Kolmogorov value of −5/3, that of hydrodynamic turbulence.

Simultaneous interplanetary scintillation and Heliospheric Imager observations of a coronal mass ejection [PDF]
, 2008 We describe simultaneous Interplanetary Scintillation (IPS) and STEREO Heliospheric Imager (HI) observations of a coronal mass ejection (CME) on 16 May 2007. Strong CME signatures were present throughout the IPS observation.

Parallel and perpendicular cascades in solar wind turbulence [PDF]
, 2005 MHD-scale fluctuations in the velocity, magnetic, and density fields of the solar wind are routinely observed. The evolution of these fluctuations, as they are transported radially outwards by the solar wind, is believed to involve both wave and ...

Kinetic helicity and MHD turbulence [PDF]
, 2000 The issue of dynamical anisotropy in helical three-dimensional magnetohydrodynamic turbulence with a mean magnetic field B₀ is investigated. Using high-resolution direct numerical simulations, we follow the evolution of various isotropic initial states ...
