Conference explores relationship between geomagnetic storms and substorms

Authors


Abstract

The terrestrial magnetosphere is strongly disturbed by solar plasma, especially during periods of increased solar activity These disturbances constitute geomagnetic storms and substorms and may damage many technological systems, depending on the intensity of the geomagnetic activity Substorms have long been considered to be essential components of geomagnetic storms, but recent studies of the solar windmagnetosphere system are leading to a rethinking of their relationship.

About 100 scientists from around the world gathered near Mumbai, India, last March for the AGU Chapman Conference on Storm-Substorm Relationships, to assess current understanding of the relationship between these two major components of geomagnetic activity. The recent data from space missions and ground-based observations and developments in theory and modeling were extensively reviewed and critically examined to assess the advances and to identify key future directions.
