Solar storms consist of interlinked space weather phenomena such as coronal mass ejections (CMEs), solar flares and solar energetic particle (SEP) events. Earth-bound interplanetary CMEs can trigger geomagnetic storms associated with intensification and expansion of the auroral oval to lower latitudes and with geomagnetically induced currents. SEP radiation storms are associated with solar flares and/or the shock waves driven by CMEs. The most energetic class of SEP events, requiring acceleration processes that produce particles with energies of at least ~500 MeV upon entry in the Earth's atmosphere, results occasionally in ground level enhancement events, registered by particle detectors, such as ionization chambers, muon, and neutron monitors. Geomagnetic and SEP radiation storms result both in severe changes of the space weather conditions with major consequences on technology and human health. This session covers the effects of solar storms on all time-scales ranging from hours to millenia. Specifically, it will consider what short-term effects can teach us in regard to long-term effects and vice versa. Papers on methods and applications for predicting solar storms and their heliospheric propagation and effects on the Earth environment, based on real-time satellite and/or ground-based data, and developed for an operational setting are highly welcome. Cross-disciplinary abstracts that link the various space weather phenomena under the umbrella of going from science to operations are encouraged.
