Magnetosheath study: INTERBALL observation

Advances in Space Research, 2000
Abstract The fundamental question of the solar wind magnetosphere coupling is how the solar wind and IMF are modified before they hit the magnetopause. Various models have been proposed to describe the magnetosheath flow but none of them includes the presence of the foreshock region.

The cusp-magnetosheath interface

Journal of Geophysical Research, 1976
Three Heos 2 passes through the distant cusp-magnetosheath transition in summer 1973 are described. By combining data from three different experiments on board Heos 2 it has been possible to identify a distinct transition from a ‘stagnant’ plasma (the distant cusp) to a region of ‘reduced flow’ magnetosheath.

Magnetosheath whistler turbulence

Journal of Geophysical Research: Space Physics, 1985
Magnetic field short‐period fluctuations δB are observed throughout the earth's magnetosheath. We report a study of these fluctuations with frequencies 20 < f < 1000 Hz in which the turbulence has a broadband spectrum δB²(f) varying approximately as f−α, where α ∼ 4±0.5, or consists of a narrowband intermediate frequency peak superimposed on the ...

Near-magnetopause magnetosheath in 3D gasdynamic module of the numerical magnetosheath–magnetosphere model

Advances in Space Research, 2016
Abstract This paper describes an approach to a theoretical interpretation of Interball-1 satellite measurements data in two cases of the satellite’s crossings of the magnetosheath. An interpretation is made of both the measured crossings of the magnetosheath boundaries and the behavior of the registered plasma parameters. In our case, it is the value

Magnetosheath electrostatic turbulence

Journal of Geophysical Research: Space Physics, 1979
By using measurements with the University of Iowa plasma wave experiment on the Imp 6 satellite a study has been conducted of the spectrum of electrostatic plasma waves in the terrestrial magnetosheath. Electrostatic plasma wave turbulence is almost continuously present throughout the magnetosheath with broadband (20 Hz to 70 kHz) rms field intensities

Comparison of a new magnetosphere–magnetosheath model with Interball-1 magnetosheath plasma measurements

Planetary and Space Science, 2005
Abstract We report a testing of the earlier developed in the Institute of Mechanics of the Bulgarian Academy of Sciences numerical data-based 3D model of the system magnetosphere–magnetosheath with real satellite data. The model is a result of a self-consistent solution of two tasks: (i) Chapman–Ferraro problem for an arbitrary 3D magnetopause with ...

MHD-modelling of the magnetosheath

Planetary and Space Science, 2002
Abstract A short discussion of some problems of magnetosheath physics is presented. In particular, anisotropic MHD models of the magnetosheath are discussed. A method to estimate the value of the characteristic relaxation time (τ) of the proton temperature anisotropy from experimental data is proposed.

MHD properties of magnetosheath flow

Planetary and Space Science, 2002
Abstract We discuss four aspects of magnetosheath flow that require MHD for their calculation and understanding. We illustrate these aspects with computations using a numerical MHD code that simulates the global magnetosphere and its magnetosheath.

Magnetosheath Interaction with the High Latitude Magnetopause

Surveys in Geophysics, 2005
We present both statistical and case studies of magnetosheath interaction with the high-latitude magnetopause on the basis of Interball-1 and other ISTP spacecraft data. We discuss those data along with recently published results on the topology of cusp-magnetosheath transition and the roles of nonlinear disturbances in mass and energy transfer across ...

Magnetic fields of the magnetosheath

Reviews of Geophysics, 1976
The magnetic field of the magnetosheath is most naturally discussed in terms of its steady state and its fluctuating components. The theory of the steady state field is quite well developed, and its essential features have been confirmed by observations.
