| Zusammenfassung |
| 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 magnetopause subsolar point
(p⊥/p\Vert ≌ 10). The pressure
anisotropy is caused by two factors: particles with small pitch angles (V\Vert>V⊥)
which travel along the magnetic field lines away from the equatorial plane of
the magnetosheath; and particles, after crossing the bowshock, which reach the
bulk velocity component directed along the magnetic field lines again, away from
the magnetosheath equatorial plane. This velocity increases with increasing
distance from the subsolar point of the bowshock, and does not permit particles
with large pitch angles (V⊥>V\Vert)
to move toward the equatorial plane. |
