The Configuration of Dayside Merging

  • Conference paper
Dynamics of the Magnetosphere

Part of the book series: Astrophysics and Space Science Library ((ASSL,volume 78))

Abstract

The development of the geometry of interplanetary magnetic field lines of force merging with geomagnetic field lines at the dayside magnetopause is traced from Dungey’s picture of merging at the subsolar point to a three-dimensional picture in which merging occurs along curved lines that emanate from the polar cusps. The new merging configuration is shown to be consistent with recent observations of flux transfer at the dayside magnetopause and of convection patterns at high-latitudes. In terms of a bimodal model of the magnetosphere incorporating the new merging configuration, it is estimated from observations that the contributions to convection from merging and viscous interaction are about equal.
