Correlation lengths, the Ultrascale, and the spatial structure of interplanetary turbulence
AIP Conference Proceedings, 1999Characteristic length scales can be employed to describe the large scale structural and statistical features of solar wind plasma turbulence. At least two outer scales of interplanetary turbulence, the correlation scale and an independent quantity that has been called the “Ultra scale,” have application in the theory of field line random walk and ...

Impact of interplanetary shock on parameters of plasma turbulence in the Earth’s magnetosheath
Geomagnetism and Aeronomy, 2017Data from the BMSW spectrometer, which measures the ion flux value and sometimes plasma parameters with a time resolution of 31 ms, allow the study of the parameters of turbulence of the solar wind and magnetosheath plasma on kinetic scales. In this work, the frequency spectra of the ion flux fluctuations before and after recording the interplanetary ...

A power spectral analysis of turbulence associated with interplanetary shock waves
AIP Conference Proceedings, 2013We calculate the power spectra densities of magnetic field fluctuations associated with interplanetary shock waves at 1AU, utilizing in-situ magnetic field measurements from spacecraft ACE and Wind. We derive related quantities both upstream and downstream of a shock as a function of time/distance away from the shock passage.

Interplanetary MHD turbulence: A wavelet approach
1997Using solar wind data recorded by the Helios-2 spacecraft at 0.3 AU we analyse MHD turbulence by means of continuous wavelet transform. This new technique, differently from FFT technique, provides a good spatial and temporal resolution. This feature allows to study in more detail local properties of solar wind turbulence. Power density spectra computed

Turbulence spectrum of interplanetary magnetic fluctuations and the rate of energy cascade
AIP Conference Proceedings, 2007There is growing evidence that a turbulent cascade of energy from large to small scales accounts for the dissipation of fluid energy (magnetic and velocity fluctuations) that heats the background plasma. However, much remains to be done to understand the dynamics of that cascade.

Turbulence associated with interplanetary shock waves within 1 AU
Advances in Space Research, 1984Abstract The nature and strength of low-frequency MHD turbulence in association with fast-forward, oblique shock waves is investigated using Helios 1 magnetic field and plasma data. Power and coherence spectra were computed and compared for the pre- and post-shock regions for the magnetic field, velocity and density fluctuations in the frequency ...

Radar detection of interplanetary shocks: Scattering by anisotropic Langmuir turbulence
Advances in Space Research, 2010Earth-directed interplanetary shocks associated with Coronal Mass Ejections (CMEs) are known to have a severe impact on the magnetosphere, causing strong geomagnetic storms and substorms. Hence, early detection of such shocks is important. Here we study the feasibility of radar detection of interplanetary shocks.
