Diagnostics of the High-Latitude Ionosphere and Spatiotemporal Dynamics of Auroral Precipitations
摘要
Abstract
High-latitude observations from the Polar Geophysical Institute are used to study the development of a typical auroral substorm that occurred on September 13, 2013. According to satellite data, the event was linked to parameters of the solar wind and physical domains and boundaries of the magnetosphere. Characteristics of the spatial structure of polar auroras (scaling indices, anisotropy) are determined for typical auroral structures (quiet and rayed arcs, breakup, pulsating bands, and omega structures).
