Structure of the Turbulent Interplanetary Magnetic Field [PDF]
We show that two widely used but apparently different models of the turbulent interplanetary magnetic field are closely related. One of these is the so-called quasi-static turbulence model, in which interplanetary magnetic field fluctuations are generated at a source surface near the Sun by random transverse plasma motions (such as supergranulation at ...

Kinematic models of the interplanetary magnetic field [PDF]
Current knowledge on the description of the interplanetary magnetic field is reviewed with an emphasis on the kinematic approach as well as the analytic expression.

Cosmic ray fluctuations and MHD waves in the solar wind
During large-scale solar wind disturbances, variations in galactic cosmic rays with periods from several minutes to 2–3 hours, which are called cosmic ray fluctuations in the scientific literature, often occur.

The interaction between interplanetary (IP) shocks and the solar wind has been studied in the past for the understanding of energy dissipation mechanisms within collisionless plasmas.

The discovery of very prominent magnetic kinks/switchbacks in the solar wind within 0.3 au has become a scientific highlight of the Parker Solar Probe (PSP) mission. This discovery points at the promising impact of small-scale solar activity on the inner

von Karman Correlation Similarity of the Turbulent Interplanetary Magnetic Field
Abstract A major development underlying much of hydrodynamic turbulence theory is the similarity decay hypothesis due to von Karman and Howarth here extended empirically to magnetic field fluctuations in the solar wind. In similarity decay the second-order correlation experiences a continuous transformation based on a universal ...

Interpretation of Flat Energy Spectra Upstream of Fast Interplanetary Shocks
Interplanetary shocks are large-scale heliospheric structures often caused by eruptive phenomena at the Sun, and represent one of the main sources of energetic particles.
