Alternate Definitions for GeomagneticStorm

A magnetospheric disturbance typicallydefined by variations in the horizontal component of the Earth's surfacemagnetic field. The variation typically starts with a field enhancementassociated with a solar wind pressure pulse and continues with a fielddepression associated with an enhancement of the diamagnetic magnetosphericring current.
