Information - ST5.5 Inter-hemispheric similarities and asymmetries in geospace phenomena
Event Information
Measurements of high-latitude electromagnetic fields, currents, and
auroras in the conjugate hemispheres have revealed latitudinal,
longitudinal and hemispheric asymmetries. Such global-scale MI
coupling effects should be predicted by global models, yet many
fundamental questions remain. For example, can asymmetries in auroral
intensity and morphology be accounted for by tilt angle and IMF
influence on the magnetosphere? Or Is the energy input from the solar
wind to the magnetosphere different in the two hemispheres? Or How
well are these effects accounted for in magnetic field models? Or Does
the state of the ionosphere play a significant role in
dayside/nightside asymmetries in Joule heating. Conjugate imaging from
space (IMAGE and Polar) as well as measurements from ground-based
facilities are used to address these questions. As we are approaching
the International Polar Year the session will especially welcome
presentations from multinational and interdisciplinary research
programs like ICESTAR, IHY and CAWSES. In addition to final results we
will be interested to hear discussion about the remaining outstanding
questions and suggestions on how they could be solved with the massive
data sets which we now have in our hands.
