Substorm associated radar auroral surges: a statistical study and possible generation model

Abstract

Substorm-associated radar auroral surges (SARAS) are a short lived (15±90 minutes) and spatially localised ( 5° of latitude) perturbation of the plasma convection pattern observed within the auroral Eregion. The understanding of such phenomena has important rami®cations for the investigation of the larger scale plasma convection and ultimately the coupling… (More)
