本文综述了近年来星载气体分析仪对高层大气扰动的研究结果。根据这些测量，磁层活动导致两个不同的扰动区的发展。高纬度和中纬度地区的特点是增加了较重的成分Ar，N2和O2，由高度依赖的行为的O，和由显着减少的He。大气层的反应时间比一个轨道周期小得多。在低纬度地区，观察到所有成分的适度增加。大气层和电离层数据之间的比较表明，与正面影响相反，负面电离层风暴与中性成分的变化密切相关。此外，模型计算完全支持这两种现象之间的因果关系。鉴于这种相关性，大气和负电离层扰动效应有某些共同的变化。这些变化包括磁暴强度、磁场位置、当地时间和季节的系统变化。虽然目前可用的经验和理论模型是相当能够再现所观察到的大气扰动的基本属性，这些算法是不够复杂的数据的更详细的描述。
This review summarizes some of the recent results on the disturbed upper atmosphere obtained by satellite-borne gas analyzers. According to these measurements, magnetospheric activity leads to the development of two different disturbance zones. The high- and middle-latitude region is characterized by an increase in the heavier constituents Ar, N2, and O2, by a height-dependent behavior of O, and by a significant decrease of He. The reaction time of the atmosphere is much smaller than one orbital period. At lower latitudes a moderate increase of all constituents is observed. A comparison between atmospheric and ionospheric data demonstrates that, in contrast to positive effects, negative ionospheric storms are closely coupled to changes in the neutral composition. In addition, model calculations fully support a causal relation between both phenomena. Given this correlation, atmospheric and negative ionospheric disturbance effects have certain variations in common. These include systematic changes with the magnetic storm intensity, with magnetic position, with local time, and with season. Whereas the presently available empirical and theoretical models are quite capable of reproducing the basic properties of the observed atmospheric perturbations, these algorithms are not sophisticated enough for a more detailed description of the data.
