Abstract

This study is aimed at statistically analyzing the ionospheric response to geomagnetic storms based on the data from the global ionospheric maps (GIMs). The global electron content and average zonal values of the total electron content for five latitudinal zones (equatorial zone, mid-latitude zones of the Northern and Southern Hemispheres, and high-latitude zones of the Northern and Southern Hemispheres) are selected as the ionospheric characteristics that are calculated from the global characteristics by using GIMs. The results of the statistical analysis are discussed in terms of the concept of an ionospheric/thermospheric storm, within which ionospheric disturbances are a consequence of the changes in the thermospheric parameters (neutral composition of the thermosphere and wind). The contradictions in the concept of a thermospheric/ionospheric storm are discussed from the standpoint of the methodological aspects of the statistical analysis and effects that are beyond this concept.

基于全球电离层地图数据的电离层对地磁风暴响应的统计分析

摘要

这项研究旨在基于全球电离层图（GIM）的数据，对电离层对地磁风暴的响应进行统计分析。选择五个纬度区（赤道带，北半球和南半球的中纬度区域以及北半球和南半球的高纬度区域）的总电子含量和总电子含量的平均纬向值作为电离层特征使用GIM从全局特征计算得出的值。将根据电离层/热层风暴的概念来讨论统计分析的结果，其中电离层干扰是热层参数（热层和风的中性成分）变化的结果。
