The authors present a review of geomagnetic storm research. They examine the interaction of the solar wind with the magnetosphere. They argue that a storm results from the extended interaction of the solar wind/magnetosphere when a strong convection electric field is generated, which is able to perturb the ring current above some threshold level, triggering the event. They touch on interrelationships of the solar wind/magnetosphere/ionosphere as it bears on this problem, and offer ideas for continuing research directions to address the origin of geomagnetic storms.
