Superposition of Doppler‐Shifting Magnetopause Kelvin‐Helmholtz Modes Through Dynamic Mode Decomposition of a Global MHD Simulation

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract The Kelvin‐Helmholtz instability (KHI) mediates the viscous‐like solar‐terrestrial interaction by generating magnetopause surface waves that quickly become non‐linear. Basic theory predicts the locally most‐unstable linear wave dominates.

Non-Gaussianity and cross-scale coupling in interplanetary magnetic field turbulence during a rope–rope magnetic reconnection event [PDF]

, 2018
. In a recent paper (Chian et al., 2016) it was shown that magnetic reconnection at the interface region between two magnetic flux ropes is responsible for the genesis of interplanetary intermittent turbulence. The normalized third-order moment (skewness)

Turbulence, intermittency and cross-scale energy transfer in an interplanetary coronal mass ejection

, 2022
Solar wind measurements carried out by NASA's Wind spacecraft before, during and after the passing of an interplanetary coronal mass ejection (ICME) detected on 12-14 September 2014 have been used in order to examine several properties of ...

Second‐Scale Formation of Non‐Field‐Aligned Plasma Irregularities Observed From a High‐Altitude 43‐Cassiopeiids Fireball

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract High‐altitude optical meteors initiating above 150 km are exceedingly rare, with confirmed observations largely confined to the Leonids. Using the Meteor and ionospheric Irregularity Observation System, we recorded a bright 43‐Cassiopeiids fireball with heterogeneous material. It initiated luminously at an exceptional altitude of 157.8 ± $\pm $

A Fokker–Planck Framework for Studying the Variability of the Magnetic Field Direction in the Alfvénic Streams of the Solar Wind

The Astrophysical Journal Letters
Turbulent rotations of the magnetic field vector are observed in the Alfvénic streams of the solar wind where the magnetic field strength remains close to a constant. They can lead to reversals of the radial magnetic field component or switchbacks. It is

“Caterpillar” ULF Waves in the Dusk Side Sub‐Auroral Region: Conjugate Observations With SuperDARN, Arase and Ground Magnetometers

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract On 23 November 2022, during exceptionally quiet geomagnetic conditions, a distinct ultra‐low frequency (ULF) wave in the Pc5 band (∼2.4 mHz) was observed in the duskside sub‐auroral region by two Canadian SuperDARN (Super Dual Auroral Radar Network) radars.

Third-moment descriptions of the interplanetary turbulent cascade, intermittency and back transfer [PDF]

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2015
We review some aspects of solar wind turbulence with an emphasis on the ability of the turbulence to account for the observed heating of the solar wind. Particular attention is paid to the use of structure functions in computing energy cascade rates and their general agreement with the measured thermal proton heating.

Investigating Magnetosphere‐Ionosphere‐Thermosphere Coupling During Geomagnetic Storms With a Novel Thermospheric Disturbance Index

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract This study introduces a novel thermospheric disturbance index, JpT ${J}_{p}^{T}$, designed to describe density variations during geomagnetic storms. The index is constructed by applying the spectral whitening method to thermospheric density data derived from precise orbit determination of satellites from 2015 to 2019.
