Observations of Waves and Structures by Frequency–Wavenumber Spectrum in Solar Wind Turbulence

The Astrophysical Journal, 2023
A well-known shortcoming of single-spacecraft spectral analysis is that only the 1D wavenumber spectrum can be observed, assuming the characteristic wave propagation speed is much smaller than the solar wind flow speed.

Solar cycle changes of large-scale solar wind structure

, 2011
In this paper, I present the results on large-scale evolution of density turbulence of solar wind in the inner heliosphere during 1985 - 2009. At a given distance from the Sun, the density turbulence is maximum around the maximum phase of the solar cycle

One-point statistics and intermittency of induced electric field in the solar wind

, 2004
The interplanetary induced electric field e=vxb is studied, using solar wind time series. The probability distribution functions (PDFs) of the electric field components are measured from the data and their non-gaussianity is discussed.

The Influence of Magnetic Turbulence on the Energetic Particle Transport Upstream of Shock Waves

Atmosphere, 2021
Energetic particles are ubiquitous in the interplanetary space and their transport properties are strongly influenced by the interaction with magnetic field fluctuations.

Sunward-propagating Alfv\'enic fluctuations observed in the heliosphere [PDF]

, 2016
The mixture/interaction of anti-sunward-propagating Alfv\'enic fluctuations (AFs) and sunward-propagating Alfv\'enic fluctuations (SAFs) is believed to result in the decrease of the Alfv\'enicity of solar wind fluctuations with increasing heliocentric ...

A nonextensive entropy approach to solar wind intermittency

, 2004
The probability distributions (PDFs) of the differences of any physical variable in the intermittent, turbulent interplanetary medium are scale dependent.

Influence of the Eccentric Geomagnetic Dipole on Longitude Variations of Compressional Upstream Wave Amplitudes in the Topside Ionosphere: Results From the MSS‐1A Satellite

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Based on 2‐year magnetic data from the Macau science satellite, we investigate the compressional Pc3‐4 pulsations (between 16 and 100 mHz) driven by upstream waves (UWs). Our results confirm larger UWs amplitudes in the South Atlantic Anomaly (SAA) longitudes, agreeing with previous missions.

Characterization of the Transmission and Generation of Turbulence at Interplanetary Shocks

The Astrophysical Journal
We study the transmission and characteristics of turbulent magnetohydrodynamic (MHD) fluctuations from upstream to downstream regions of interplanetary (IP) shocks using the linear mode decomposition (LMD) technique of G. P. Zank et al.

INFLUENCE OF THE SOLAR WIND ON INTERFEROMETRIC OBSERVATIONS AT THE DECAMETER WAVELENGTHS [PDF]

Radio Physics and Radio Astronomy, 2020
Purpose: The effect of the Earth’s ionosphere and interplanetary plasma on the radio astronomy observations, in particular, interferometric ones, at decameter waves has been investigated.
