Spatial dependence of magnetopause energy transfer: Cluster measurements verifying global simulations [PDF]

Annales Geophysicae, 2011
We investigate the spatial variation of magnetopause energy conversion and transfer using Cluster spacecraft observations of two magnetopause crossing events as well as using a global magnetohydrodynamic (MHD) simulation GUMICS-4.

Four-spacecraft determination of magnetopause orientation, motion and thickness: comparison with results from single-spacecraft methods [PDF]

Annales Geophysicae, 2004
In this paper, we use Cluster data from one magnetopause event on 5 July 2001 to compare predictions from various methods for determination of the velocity, orientation, and thickness of the magnetopause current layer. We employ established as well as

Drift turbulence, particle transport, and anomalous dissipation at the reconnecting magnetopause [PDF]

Physics of Plasmas, 2018
Using fully kinetic 3D simulations, the reconnection dynamics of asymmetric current sheets are examined at the Earth's magnetopause. The plasma parameters are selected to model MMS magnetopause diffusion region crossings with guide fields of 0.1, 0.4 ...

Coordinated polar spacecraft, geosynchronous spacecraft, and ground-based observations of magnetopause processes and their coupling to the ionosphere [PDF]

Annales Geophysicae, 2004
In this paper, we present in-situ observations of processes occurring at the magnetopause and vicinity, including surface waves, oscillatory magnetospheric field lines, and flux transfer events, and coordinated observations at geosynchronous orbit by ...

Magnetic Field Gradient Across the Flank Magnetopause

Frontiers in Astronomy and Space Sciences, 2021
Magnetic pressure inside the magnetopause is usually balanced with a sum of thermal plasma and magnetic pressures on the magnetosheath side. However, observations reveal that the magnetosheath magnetic field can be frequently larger than that in the ...

A time-dependent three-dimensional dayside magnetopause model based on quasi-elastodynamic theory [PDF]

Geoscientific Model Development
The interaction between the solar wind and Earth's magnetosphere is a critical area of research in space weather and space physics. Accurate determination of the magnetopause position is essential for understanding magnetospheric dynamics. While numerous

Ion escape from the high latitude magnetopause: analysis of oxygen and proton dynamics in the presence of magnetic turbulence [PDF]

Annales Geophysicae, 2007
Recent Cluster observations of the vicinity of the high latitude magnetopause indicate the presence of beams of singly charged oxygen ions, which are of ionospheric origin.

20 Years of Cluster Observations: The Magnetopause [PDF]

Journal of Geophysical Research: Space Physics, 2021
AbstractThe terrestrial magnetopause forms the boundary between the solar wind plasma with its embedded interplanetary magnetic field on one side, and the terrestrial magnetosphere, dominated by Earth's dipole field, on the other side. It is therefore a key region for the transfer of mass, momentum, and energy from the solar wind to the magnetosphere ...

The Cluster spacecrafts' view of the motion of the high-latitude magnetopause [PDF]

Annales Geophysicae
The magnetopause is the boundary between the interplanetary magnetic field and the terrestrial magnetic field. It is influenced by different solar-wind conditions, which lead to a change in the shape and location of the magnetopause.
