Anisotropic MHD turbulence 8 Cosmic rays and the solar cycle • Cosmic ray flux at the Earth is modulated by the solar cycle • This is due to variations in the magnetic barrier in the solar system • Waves and turbulence in the solar wind form a key part of this barrier.
Physics of the Inner Heliosphere gives for the first time a comprehensive and complete summary of our knowledge of the inner solar system. Using data collected over more than 11 years by the HELIOS twin solar probes, one of the most successful ventures in unmanned space exploration, the authors have compiled six extensive reviews of the physical processes of the inner heliosphere and their.

• The solar wind is a vast turbulent laboratory: Alfvén waves, active cascades, anisotropy, intermittency • Small scale solar wind turbulence exists (Hall MHD scales) Useful for the inner corona • Questions: initial forcing, cross-helicity, power law exponents • Lack of data to understand the 3D structure of turbulence.
The recent work of Burlaga / 3 7 / opens in my mind a very promising avenue to analyse and understand solar wind turbulence from a new theoretical vantage point. Static structure functions have even been calculated analytically / 3 8 / for Navier-Stokes flows.
This approach may also be useful for MHD turbulence. Marsch, “MHD turbulence in the solar wind,” in Physics of the Inner Heliosphere, edited by R. Schwenn and E. Marsch (Springer-Verlag, New York, ), p.
Google Scholar The solar wind thus provides one example of wave heating. Waves have the advantage of being able to heat the chromosphere and photospheric magnetic flux tubes on their way to the corona.
MHD turbulence (as observed in the solar wind) or resonance absorption seem to provide adequate dissipation mechanisms. A problem with wave theories is that.
solar wind. Their abundance and short timescales as seen by PSP in its ﬁrst encounter is a new observation, and their precise origin is still unknown. By analyzing these MHD invariants as a function of the wavelet scale, we show that magnetohydrodynamic (MHD) waves do indeed follow the local mean magnetic ﬁeld through.
Magnetic field and plasma data, obtained by the Helios 1 and 2 spacecraft in the solar wind near AU during the years tohave been analyzed by calculating 12 kinds of spectra related to the Elsässer variables, δZ + = δV + δV A, and δZ − = δV − δV A, where δV and δV A are the bulk velocity and Alfvén velocity fluctuations, respectively.
The variation of the power spectra (e ±) of the fluctuating Elsässer variables δZ ± with the solar wind velocity has been examined by either individual case study or statistical analysis with Helios data obtained near solar is found, when going from high‐speed to low‐speed wind, that: 1.) The slopes of both energy spectra systematically increase toward the value given by.

1 INTRODUCTION. It is long known that large-scale turbulent fluctuations in the solar wind are dominated by the Alfvén waves (AWs; Belcher & Davis ).Since the AW represents an exact solution of the incompressible ideal magnetohydrodynamics (MHD), the energy cascade in the AW turbulence is governed by non-linear interactions among counter-propagating waves (Iroshnikov ; Kraichnan.
Turbulence-generated coherent structures and waves MHD-generated turbulence. A dramatic change of the plasma transport has been found, going from the interacting with the turbulent solar wind, to the largest scales of radio relics in galaxy clusters .

In future. Multi-order structure functions in the solar wind are reported to display a monofractal scaling when sampled parallel to the local magnetic field and a multifractal scaling when measured perpendicularly.
Whether and to what extent will the scaling anisotropy be weakened by the enhancement of turbulence amplitude relative to the background magnetic strength. In this study, based on two runs of. A main motivation was the attempt to relate more closely the theoretical un derstanding of MHD waves and turbulence (both weak and strong) with the most recent observations in space plasmas.
