Coexistence of weak and strong wave turbulence in incompressible Hall magnetohydrodynamics
Romain Meyrand, Khurom H. Kiyani, Ozgur D. Gurcan +1
We report a numerical investigation of three dimensional, incompressible, Hall magnetohydrodynamic turbulence with a relatively strong mean magnetic field. Using helicity decomposi…
Nature of the MHD and kinetic scale turbulence in the magnetosheath of Saturn: Cassini observations
L. Z. Hadid, F. Sahraoui, K. H. Kiyani +5
Low frequency turbulence in Saturn's magnetosheath is investigated using in-situ measurements of the Cassini spacecraft. Focus is put on the magnetic energy spectra computed in the…
Direct Evidence of the Transition from Weak to Strong MHD Turbulence
Romain Meyrand, Sebastien Galtier, Khurom H. Kiyani
One of the most important predictions in magnetohydrodynamics (MHD) is that in the presence of a uniform magnetic field a transition from weak to strong wave turbu…
Multi-Spacecraft Measurement of Turbulence within a Magnetic Reconnection Jet
K. T. Osman, K. H. Kiyani, W. H. Matthaeus +3
The relationship between magnetic reconnection and plasma turbulence is investigated using multipoint in-situ measurements from the Cluster spacecraft within a high-speed reconnect…
Intermittency in Weak Magnetohydrodynamic Turbulence
Romain Meyrand, Khurom H. Kiyani, Sebastien Galtier
Intermittency is investigated using decaying direct numerical simulations of incompressible weak magnetohydrodynamic turbulence with a strong uniform magnetic field and…
Anisotropic Intermittency of Magnetohydrodynamic Turbulence
K. T. Osman, K. H. Kiyani, S. C. Chapman +1
A higher-order multiscale analysis of spatial anisotropy in inertial range magnetohydrodynamic turbulence is presented using measurements from the STEREO spacecraft in fast ambient…
Proton Kinetic Effects and Turbulent Energy Cascade Rate in the Solar Wind
Kareem T. Osman, William H. Matthaeus, Khurom H. Kiyani +2
The first observed connection between kinetic instabilities driven by proton temperature anisotropy and estimated energy cascade rates in the turbulent solar wind is reported using…
Hybrid Focal Stereo Networks for Pattern Analysis in Homogeneous Scenes
Emanuel Aldea, Khurom H. Kiyani
In this paper we address the problem of multiple camera calibration in the presence of a homogeneous scene, and without the possibility of employing calibration object based method…
Global scale-invariant dissipation in collisionless plasma turbulence
K. H. Kiyani, S. C. Chapman, Yu. V. Khotyaintsev +1
A higher-order multiscale analysis of the dissipation range of collisionless plasma turbulence is presented using in-situ high-frequency magnetic field measurements from the Cluste…
Pseudo-nonstationarity in the scaling exponents of finite interval time series
K. H. Kiyani, S. C. Chapman, N. W. Watkins
The accurate estimation of scaling exponents is central in the observational study of scale-invariant phenomena. Natural systems unavoidably provide observations over restricted in…
Self-similar signature of the active solar corona within the inertial range of solar wind turbulence
K. Kiyani, S. C. Chapman, B. Hnat +1
We quantify the scaling of magnetic energy density in the inertial range of solar wind turbulence seen in-situ at 1AU with respect to solar activity. At solar maximum, when the cor…
A method for extracting the scaling exponents of a self-affine, non-Gaussian process from a finite length timeseries
K. Kiyani, S. C. Chapman, B. Hnat
We address the generic problem of extracting the scaling exponents of a stationary, self-affine process realised by a timeseries of finite length, where information about the proce…
Eulerian spectral closures for isotropic turbulence using a time-ordered fluctuation-dissipation relation
W. D. McComb, K. Kiyani
Procedures for time-ordering the covariance function, as given in a previous paper (K. Kiyani and W.D. McComb Phys. Rev. E 70, 066303 (2004)), are extended and used to show that th…
