| Summary: | Enhancements in the auroral electrojets
associated with magnetospheric substorms result from those in either the
electric field or the ionospheric conductivities, or both. Their relative
importance varies significantly, even during a single substorm, depending on the
location as well as on the substorm phases. It is predicted that different parts
of the electrojets tend to respond in different ways to substorm activity. The
unprecedented, unique opportunity for CLUSTER spacecraft observations of
electric/magnetic fields and precipitating particles, combined with radar
measurements of ionospheric quantities and with ground magnetometers, will
provide us with crucial information regarding the physical nature of the
separation between the "electric field-dominant'' and
"conductivity-dominant'' auroral electrojets. This study also discusses the
implications of these two auroral-electrojet components in terms of solar
wind-magnetosphere-ionosphere interactions. |
