Numerical modelling of the Earth’s magnetosheath for different IMF orientations
TLDR
In this paper, a new magnetosheath numerical MHD model has been developed which calculates solar wind flow around a paraboloidal obstacle, and the magnetic barrier may almost disappear for a special interplanetary magnetic field orientation nearly aligned with the solar wind velocity.About:

Magnetic Turbulence in the Geospace Environment
Gaetano Zimbardo,Antonella Greco,Luca Sorriso-Valvo,Silvia Perri,Zoltán Vörös,G. D. Aburjania,Kh. Z. Chargazia,Olga Alexandrova +7 more
TL;DR: In this article, a large share of magnetic turbulence in the geospace environment is generated locally, as due for instance to the reflected ion beams in the ion foreshock, to temperature anisotropy in the magnetosheath and the polar cusp regions, to velocity shear, and to magnetic reconnection at the magnetopause and in magnetotail.

Why does the subsolar magnetopause move sunward for radial interplanetary magnetic field
TL;DR: In this article, the distribution of different pressure components (dynamic, thermal, magnetic) in the magnetosheath along the Sun-Earth line for northward and radial interplanetary magnetic field (IMF) orientations with motivation to explain an unusual location and shape of the magnetopause often observed during the intervals of the radial IMF.

Interplanetary shock in the magnetosheath: Comparison of experimental data with MHD modeling
A. Koval,Jana Safrankova,Zdeněk Němeček,Andrey Samsonov,Lubomír Přech,John D. Richardson,M. Hayosh +6 more
TL;DR: In this article, the authors compare profiles of the magnetic field and plasma parameters observed experimentally by several spacecraft in the solar wind and magnetosheath with profiles generated by two MHD numerical models.

Proton temperature anisotropy in the magnetosheath: comparison of 3-D MHD modelling with Cluster data
TL;DR: In this article, the authors make numerical simulations of these magnetosheath crossings, using a three-dimensional double-adiabatic MHD model of the magnetoheath and assuming that the proton temperature anisotropy is bounded by the kinetic thresholds of the Alfven proton cyclotron instability and of the mirror instability.

Interplanetary shock transmitted into the Earth's magnetosheath: Cluster and Double Star observations
G. Pallocchia,Andrey Samsonov,M. B. Bavassano Cattaneo,Maria Federica Marcucci,H. Rème,Chris Carr,J. B. Cao +6 more
TL;DR: In this article, the impact of an interplanetary shock wave (IS) on the terrestrial bow shock has been analyzed and shown to be slowed down with respect to the incident IS in the Earth's reference frame.

Interplanetary Magnetic Field and the Auroral Zones
TL;DR: In this article, it was found that a model with a southward interplanetary magnetic field leads to a natural explanation of the SD currents and speculative aspects of the problem as they appear at this time are discussed.

Hydromagnetic flow around the magnetosphere
TL;DR: MHD equations applied to hypersonic flow of solar plasma around magnetosphere and approximation with simpler equations of gas dynamics were used to simulate the solar plasma in the magnetosphere.

A model of the near magnetosphere with a dawn-dusk asymmetry 1. Mathematical structure
TL;DR: In this paper, a new empirical magnetic field model has been developed, representing the variable configuration of the inner and near magnetosphere for different interplanetary conditions and the ground disturbance levels.

Depletion of solar wind plasma near a planetary boundary
B. J. Zwan,Richard A. Wolf +1 more
TL;DR: In this paper, a mathematical model is presented that describes the squeezing of solar wind plasma out along interplanetary magnetic field lines in the region between the bow shock and the effective planetary boundary (in the case of the earth, the magnetopause).

Concerning the location of magnetopause merging as a function of the magnetopause current strength
TL;DR: In this article, the authors adopt an analytical model based on previously derived formulations for magnetospheric and magnetosheath magnetic fields to determine the locations of the magnetopause where current strengths are greater than some threshold value.
