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...

We consider the phenomena of intermittent turbulence in magnetized space plasmas from the point of view of topological phase transitions involving the merging and interactions of anisotropic coherent ...
Low-frequency variability in idealised GCM experiments with circumpolar and localised storm tracks
Low-frequency variability idealised GCM experiments circumpolar localised storm tracks
2009/11/12
Idealised global circulation model simulations with circumpolar and localised (one and two) storm tracks are re-analysed to determine scaling, intermittency and phase-space structures. In a hundred ye...
The strange physics of low frequency mirror mode turbulence in the high temperature plasma of the magnetosheath
strange physics low frequency mirror mode turbulence high temperature plasma
2009/11/11
Mirror mode turbulence is the lowest frequency perpendicular magnetic excitation in magnetized plasma proposed already about half a century ago by Rudakov and Sagdeev (1958) and Chandrasekhar et al. (...
High frequency ion sound waves associated with Langmuir waves in type III radio burst source regions
High frequency ion sound waves Langmuir waves type III radio burst source regions
2009/11/11
Short wavelength ion sound waves (2-4kHz) are detected in association with the Langmuir waves (~15-30kHz) in the source regions of several local type III radio bursts. They are most probably not due t...

ultifractal imaging filtering decomposition methods Fourier frequency eigen domains
2009/11/3
The patterns shown on two-dimensional images (fields) used in geosciences reflect the end products of geo-processes that occurred on the surface and in the subsurface of the Earth. Anisotropy of these...
