PLASMAPAUSE [1 record]

Record 1 2004-03-01

English

Subject field(s)
  • Geophysics
  • Atmospheric Physics
DEF

Outer boundary of the plasmasphere, at a distance of about four Earth radii, at which there is a sharp drop in the electron density and an increase in temperature with distance.

OBS

For the Earth, the plasmapause is described as the equipotential boundary between a region dominated by the corotational electric field, where there are closed particle orbits, and a region dominated by a convective dawn-dusk electric field, where there are no closed orbits. However, the existence of such a static boundary for the dynamic magnetospheres of Uranus and Neptune has been called into question, by two dimensional guiding center calculations for particles in the magnetic equatorial plane.
