| Session Description | (ST04) This session is a general session on Cosmic rays. Cosmic rays play a significant role in numerous aspects of Space Weather through their impact on satellites during CME induced storms and relativistic solar proton events. Ground Level Enhancements can also generate Space Weather impacts at ground level. In addition the transport of cosmic rays into and through the heliosphere is generally understood but there is still much that remains to be explained. The link between cosmic ray variations and climate change has been postulated but is still controversial. The production of cosmogenic nuclei is another aspect of the impact of cosmic rays. This session will allow researchers in cosmic ray physics to present their observations and theories to the broader geophysical community and to put those observations into context. (ST14) The transport of solar energetic particles and the solar modulation of galactic cosmic rays are strongly affected by the heliospheric magnetic field and magnetic fluctuations. Recently our understanding of these processes has progressed rapidly, e.g., regarding frameworks to understand “quiescent” transport parallel and perpendicular to the mean field, the CR-B relation, small-scale features such as “dropouts,” effects of proton-amplified waves due to solar storms, magnetic fluctuations and shock acceleration, ab initio solar modulation, how pick-up ions generate magnetic fluctuations that then assist their acceleration at the termination shock, and the transport of anomalous cosmic rays. Contributions on these or any related topics are welcome. |
