Magnetospheric DC Electric Fields; Present Knowledge and Outstanding Problems to be Solved during the IMS

  • F. S. Mozer
Part of the Astrophysics and Space Science Library book series (ASSL, volume 57)


Present knowledge of the relationships between perpendicular and parallel electric fields in the ionosphere and magnetosphere and of their configurations, sources, and variations is summarised with a view to illustrating some important problems that should be addressed by IMS electric-field research programmes. These problems include determination of the source, morphology, and dynamics of parallel electric fields, the role of parallel electric fields and time-varying magnetic fields in decoupling magnetosphere-ionosphere dynamics, the configuration of the neutral line and its effect on the electric-field coupling from the interplanetary medium to the magnetosphere for arbitrary interplanetary magnetic-field directions, the importance of processes other than reconnection in producing the magnetospheric potential field, and the dynamics of polarisation and other processes that produce low-frequency turbulence and small-scale spatial structure in the electric fields.
