Local Evolution of a Prenoon Drainage Plume
Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.Abstract Plasmaspheric drainage plumes are typically observed in the postnoon sector during geomagnetic storms, but their local evolution in the prenoon sector remains poorly understood. Here, we report in situ observations from the Van Allen Probe, revealing multiple localized enhancements in cold electron density near apogee in the prenoon sector ...

Martian Magnetotail Neutral Sheet Asymmetry Driven by Heavy Planetary Pickup Ions
Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.Abstract In the induced magnetotail of Mars, the neutral sheet is an important channel for atmospheric ion escape, yet the role of heavy planetary pickup ions in shaping its geometry has been unclear. Using three‐dimensional hybrid simulations, we demonstrate that these ions induce a global neutral sheet asymmetry via mass loading.

Unraveling the Fine‐Scale Tapestry of Solar Wind at 1AU
Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.Abstract Solar wind is a complex network of distinct magnetic flux tubes, each contained and separated by a current sheet. In this study, more than 50,000 current sheets in the solar wind are identified and characterized for the first time, using multi‐point Cluster observations during solar minimum and maximum intervals.

Radial evolution of cross helicity at low and high latitudes in the solar wind [PDF]
, 2005 We employ a turbulence transport theory to the radial evolution of the solar wind at both low and high latitudes. The theory includes cross helicity, magnetohydrodynamic (MHD) turbulence, and driving by shear and pickup ions. The radial decrease of cross

Instability and transition to turbulence in a free shear layer affected by a parallel magnetic field [PDF]
, 2007 Instability and transition to turbulence in a temporally evolving free shear layer of an electrically conducting fluid affected by an imposed parallel magnetic field is investigated numerically. The case of low magnetic Reynolds number is considered.

[Nonlinear magnetohydrodynamics]. [Threshold unstable MHD activity] [PDF]
, 1992 Theoretical predictions were compared with available data from JET on the threshold unstable MHD activity in toroidal confinement devices. In particular, questions arising as to Hartmans number and the selection of a kinematic viscosity are discussed.

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.Abstract On 10 May 2024, Earth was hit by a CME that drove the largest geomagnetic storm in 20 years. Multi‐spacecraft observations previously showed that the ∼100 nT north‐south IMF bz ${b}_{z}$ variation was driven by Kelvin‐Helmholtz waves with wavelength ∼250 RE ${R}_{E}$ and reconnection jets in the ±z $\pm z$‐direction (Nykyri, 2024a, https://doi.
