Atmospheric Effects of Magnetosheath Jets

Atmosphere, 2022
We report effects in the upper high-latitude atmosphere related to the interaction of fast magnetosheath plasma streams, so-called jets, with the dayside magnetopause. The jets were observed by THEMIS mission in the dayside magnetosphere during a quiet day on 12 July 2009.

Different Transient Phenomena at the Edges of Traveling Foreshocks

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Past kinetic simulations and spacecraft observations have shown that traveling foreshocks (TFs) are bounded by either foreshock compressional boundaries (FCBs) or foreshock bubbles (FBs). Here we present four TFs with a different kind of structure appearing at one of their edges.

On the formation of a plasma pressure anisotropy in the dayside magnetosheath [PDF]

Annales Geophysicae, 1995
We present a numerical solution for the momentum equation of the magnetosheath particles that describes the distribution of the pressure anisotropy of the magnetosheath plasma in the midday meridian plane. The pressure anisotropy is a maximum near the

Determining the Magnetopause Location With SMILE‐SXI Using a Constrained Solar Wind Independent SWCX Model

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract The soft X‐ray imager (SXI) on the SMILE mission promises to revolutionize our understanding of the magnetopause by observing solar wind charge exchange emission from the magnetosheath on a global scale. The primary goal of this instrument is to infer the position and shape of the magnetopause from these images.

Sunward flow in Jupiter's magnetosheath

Geophysical Research Letters, 1980
The position of Voyager crossings of Jupiter's bow shock show a dependence on solar wind pressure to the −1/3 power. This dependence is used to calculate typical bow shock speeds of 50 km/s from Voyager solar wind plasma data. Since the bow shock and magnetopause move approximately in unison in response to solar wind pressure changes, the resulting ...

Classifying Magnetosheath Jets using MMS - Statistical Properties [PDF]

Journal of Geophysical Research: Space Physics, 2019
Abstract Using Magnetospheric Multiscale (MMS) data, we find, classify, and analyze transient dynamic pressure enhancements in the magnetosheath (jets) from May 2015 to May 2019. A classification algorithm is presented, using in situ MMS data to classify jets ( ) into ...

Unveiling the 3D Structure of Magnetosheath Jets

Monthly Notices of the Royal Astronomical Society, 2023
Magnetosheath jets represent localized enhancements in dynamic pressure observed within the magnetosheath. These energetic entities, carrying excess energy and momentum, can impact the magnetopause and disrupt the magnetosphere. Therefore, they play a vital role in coupling the solar wind and terrestrial magnetosphere. However, our understanding of the

The Dominant Role of Crustal Fields in Structuring Electromagnetic Environment Within the Martian Dayside Magnetosphere

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract Although Mars lacks an intrinsic global dipole magnetic field, the existence of crustal magnetic anomalies in the southern hemisphere causes the Martian magnetosphere to have the hybrid characteristics combining Venus‐like induced and Earth‐like intrinsic types.

Magnetic clouds' structure in the magnetosheath as observed by Cluster and Geotail: four case studies [PDF]

Annales Geophysicae, 2014
Magnetic clouds (MCs) are large-scale magnetic flux ropes ejected from the Sun into the interplanetary space. They play a central role in solar–terrestrial relations as they can efficiently drive magnetic activity in the near-Earth environment.

MMS Observations of a Compressed, Strongly Driven Magnetopause During the 2024 Mother's Day Storm

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract From 10 to 12 May 2024, a series of coronal mass ejections led to one of the strongest geomagnetic storms of the century, referred to as the Mother's Day or Gannon Storm. MMS's position on the dayside magnetosphere on 11 May provided observations of a strongly driven and compressed ∼7RE $\left(\sim 7\ {R}_{E}\right)$ reconnecting magnetopause.
