Causes and Impact of Geomagnetically Induced Currents
Session ID#: 162785
Session Description:
Space weather is a serious concern that is recognized as one of the top priority problems in today's society. The threat of space weather on strategic technological assets has rekindled interest in extreme events. To improve national preparedness, it is critical that we understand the physical processes related to extreme events in order to address key national and international objectives. In this session, we invite papers that highlight recent progress and current understanding of space weather including geomagnetic storms, electromagnetic induction studies, geomagnetically induced currents (GICs), and the GIC impact on technological systems. Submissions that focus on observations, modeling, and theoretical understanding are all encouraged.
