Abstract

Structures of an aurora are described according to its fractal dimension and anisotropy. The variability of structures is characterized by the slope of the spectrum of variation in anisotropy over time. Statistics of these characteristics are presented, based on data from the ground camera of the Polar Geophysical Institute in Apatity for 2013–2015, and referenced according to their positions inside the auroral oval and values of the geomagnetic field at the Lovozero observatory.

基于实验数据的极光椭圆结构的分形特征

根据分形维数和各向异性描述了极光的结构。结构的变异性由各向异性随时间变化谱的斜率来表征。基于2013-2015年Apatity极地地球物理研究所地面相机拍摄的数据，并参考它们在极光椭圆内的位置和Lovozero天文台的地磁场值，对这些特征进行了统计。
