Solar wind low-frequency magnetohydrodynamic turbulence:extended self-similarity and scaling laws
Solar wind low-frequency magnetohydrodynamic turbulence extended self-similarity scaling laws
2009/11/16
In this paper we review some of the work done in investigating the scaling properties of Magnetohydrodynamic turbulence, by using velocity fluctuations measurements performed in the interplanetary spa...
Intermittency,non-Gaussian statistics and fractal scaling of MHD fluctuations in the solar wind
Intermittency,non-Gaussian statistics fractal scaling MHD fluctuations solar wind
2009/11/13
This paper gives a review of some recent work on intermittency, non-Gaussian statistics, and fractal scaling of solar wind magnetohydrodynamic turbulence. Model calculations and theories are discussed...
A study of magnetic fluctuations and their anomalous scaling in the solar wind:the Ulysses fast-latitude scan
magnetic fluctuations anomalous scaling solar wind Ulysses fast-latitude scan
2009/11/12
The solar wind is a highly turbulent and intermittent medium at frequencies between 10-4 and 10-1 Hz. Power spectra are used to look at fluctuations in the components of the magnetic field at high fre...
Turbulence:mechanics and structure of anomalous scaling
Turbulence mechanics structure anomalous scaling
2009/11/12
As the finite correlation time of a force driving turbulence is taken into account, a new, dimensionless parameter occurs in the theory of turbulence. This new parameter is responsible for two differe...
Scaling in the space climatology of the auroral indices:is SOC the only possible description?
space climatology auroral indices SOC possible description
2009/11/12
The study of the robust features of the magnetosphere is motivated both by new "whole system" approaches, and by the idea of "space climate" as opposed to "space weather". We enumerate these features ...
Scaling and singularity characteristics of solar wind and magnetospheric fluctuations
Scaling and singularity characteristics solar wind magnetospheric fluctuations
2009/11/12
Preliminary results are presented which suggest that scaling and singularity characteristics of solar wind and ground-based magnetic fluctuations appear to be a significant component in the solar wind...
Anisotropic scaling features and complexity in magnetospheric-cusp:a case study
Anisotropic scaling features complexity magnetospheric-cusp
2009/11/11
Magnetospheric cusps are high-latitude regions characterized by a highly turbulent plasma, playing a special role in the solar wind-magnetosphere interaction. Here, using POLAR satellite magnetic fiel...
Scaling collapse and structure functions:identifying self-affinity in finite length time series
Scaling collapse structure functions self-affinity finite length time series
2009/11/11
Empirical determination of the scaling properties and exponents of time series presents a formidable challenge in testing, and developing, a theoretical understanding of turbulence and other out-of-eq...
Spectral scaling in the turbulent Earth's plasma sheet revisited
Spectral scaling turbulent Earth's plasma sheet
2009/11/3
Bursty bulk flow associated magnetic fluctuations exhibit at least three spectral scaling ranges in the Earth's plasma sheet. Two of the three scaling ranges can be associated with multi-scale magneto...
Scaling properties of velocity and temperature spectra above the surface friction layer in a convective atmospheric boundary layer
properties of velocity temperature spectra surface friction layer atmospheric boundary layer
2009/11/3
We report velocity and temperature spectra measured at nine levels from 1.42 meters up to 25.7 m over a smooth playa in Western Utah. Data are from highly convective conditions when the magnitude of t...
Solar cycle dependence of scaling in solar wind fluctuations
Solar cycle dependence scaling solar wind fluctuations
2009/11/2
In this review we collate recent results for the statistical scaling properties of fluctuations in the solar wind with a view to synthesizing two descriptions: that of evolving MHD turbulence and that...
