GAM3. 12 Ionospheric Structures and Processes: Their Relation
and Feedback to the Magnetosphere

The consequences arising from ionospheric conductivity changes
produced both by solar radiation and by energetic particle
precipitation will be discussed as well as the magnetospheric
effects of ionospheric dynamo fields. Because the ionosphere
is a major source of magnetospheric plasma, the sources and
upward acceleration mechanisms for cool plasma will be
considered also.

Magnetos heath

Consideration will be given to case studies and statistical
observational studies of transient events and the steady state
magnetosheath structure in the context of n ew and existing
magnetosheath models. Bow shock and magnetopause studies with
emphasis upon the magnetosheath are also invited .
GAM3 .15 Physics and Predictions of Magnetic Storms and
Disturbances

C T Russell
The session will cover geomagnetic storm phenomenology; the
physics underlying storm commencement, main phase development
and recovery; and the problem of prediction, beginning with
solar observations. A panel discussion will consider the
current state of the art and requirements for progress.
