Session Description By definition, ring current has its largest enhancements during magnetic storms.
Similarly, plasmasphere and radiation belts also have their largest variations
during magnetic storms. The causes of magnetic storms are traced back to solar
disturbances, such as coronal mass ejections (CMEs), interplanetary shocks,
and high speed solar wind streams. Even for similar solar wind conditions,
there are no identical storms. Each storm has its own characteristics. For
example, recent studies show that the acceleration mechanisms for outer
radiation belt electrons are storm-depedent: in one storm, the enhancement
of outer radiation belt electrons can be well explained by inward radial
diffusion while in situ acceleration (violating the first adiabatic invariant)
has to be invoked to explain the enhancement of the outer belt electrons during
another storm. As a result of new global and multiple-point observations from
CLUSTER, Double-Star, IMAGE, Akebono, Polar, SAMPEX, THEMIS, and in conjunction
with many spacecraft at geosynchronous orbit, as well as ground-networks such
as magnetometers, SuperDARN HF radars, a view on the storm-dependent
dynamics in the inner magnetosphere is converging. This special session
provides a forum to discuss the detailed process of this important topic:
storm-dependent dynamics in the inner magnetosphere. We seek contributions
of papers on satellite and ground based observations as well as theory/modeling
to this session.
