A model of the magnetosheath structure
proposed in a recent paper from the authors is extended to estimate the
magnetopause stand-off distance from solar wind data. For this purpose, the
relationship of the magnetopause location to the magnetosheath and solar wind
parameters is studied. It is shown that magnetopause erosion may be explained in
terms of the magnetosheath magnetic field penetration into the magnetosphere.
The coefficient of penetration (the ratio of the magnetospheric magnetic field
depression to the intensity of the magnetosheath magnetic field Bm⊥z=–Bmsin2Θ/2,
is estimated and found approximately to equal 1. It is shown that having
combined a magnetosheath model presented in an earlier paper and the
magnetosheath field penetration model presented in this paper, it is possible to
predict the magnetopause stand-off distance from solar wind parameters.
