Magnetohydrodynamic Simulation of the Interaction between Interplanetary Strong Shock and Magnetic Cloud and its Consequent Geoeffectiveness

, 2006
Numerical studies have been performed to interpret the observed "shock overtaking magnetic cloud (MC)" event by a 2.5 dimensional magnetohydrodynamic (MHD) model in heliospheric meridional plane.

Magnetopause Boundary Layers in Low Mach CME‐Driven Storm Environment

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Magnetopause boundary layers (BLs) play an important role mediating plasma and energy exchange between the solar wind/magnetosheath and Earth's magnetosphere. Energy exchange across the magnetopause is enhanced during storms, yet little work has been done investigating BLs during storms.

Automatic Identification of Interplanetary Shocks Based on Machine Learning

Space Weather
Fast forward interplanetary shocks (FFs) are one of the primary drivers of space weather events. This study presents an automated detection algorithm for FFs based on a multilayer perceptron model, utilizing in situ measurements of interplanetary ...

Variations of Heavy Ions in Different Types of Interplanetary Shocks

The Astrophysical Journal
Heavy ions upstream and downstream of interplanetary shocks are not only subject to acceleration, heating, and spatiotemporal modulation during their propagation in interplanetary space, but they can also, in turn, influence the dynamical properties of ...

Energetic ion acceleration at collisionless shocks [PDF]

An example is presented from a test particle simulation designed to study ion acceleration at oblique turbulent shocks. For conditions appropriate at interplanetary shocks near 1 AU, it is found that a shock with theta sub B n = 60 deg is capable of ...

Leaping and vortex motion of the shock aurora toward the late evening sector observed on 26 February 2023 [PDF]

Annales Geophysicae
On 26 February 2023, a shock aurora triggered by an interplanetary (IP) shock was observed in northern Scandinavia at 21 MLT (magnetic local time). Previously, ground-based observations of shock auroras have primarily been conducted on the dayside, where

Spatial dependence of the local diffusion coefficient measured upstream of the November 12, 1978 interplanetary traveling shock [PDF]

Characteristics of wuprathermal particles accelerated by quasi-parallel interplanetary traveling shocks have been generally explained in terms of a first order Fermi mechanism.

Plasma Depletion and Mirror Waves Ahead of Interplanetary Coronal Mass Ejections

, 2006
We find that the sheath regions between fast interplanetary coronal mass ejections (ICMEs) and their preceding shocks are often characterized by plasma depletion and mirror wave structures, analogous to planetary magnetosheaths.

Features of formation of small-scale wave disturbances during a sudden magnetospheric compression

Solar-Terrestrial Physics, 2017
Quasi-periodic changes of the geomagnetic field and plasma parameters in the range of Pc 5 pulsations, which occurred immediately after the interaction of interplanetary shock (IPS) with Earth’s magnetosphere in the event of April 24, 2009 at 00:53 UT ...
