The drivers, impacts and consequences of geomagnetic storms

Topic: Solar Physics

Session Title: The drivers, impacts and consequences of geomagnetic storms


Geomagnetic storms are defined by sustained energisations of the Earth’s ring current and radiation belts, and are one of the most impactful phenomena for space weather. A powerful geomagnetic storm can break satellite technologies and interfere with communication systems. 

Despite many years of study, we are still building our understanding of what exactly leads to geomagnetic storms and how geomagnetic storms play out. Each storm is unique, and so are the effects on the coupled solar wind-magnetosphere-ionosphere system. We must understand and distinguish between direct drivers, related phenomena and direct consequences.

In this topical and cross-cutting session, we invite the community to discuss the physical mechanisms which drive geomagnetic storms and how we might model and measure these. We also welcome discourse on the measurable impacts and consequences of geomagnetic storms.
