Abstract The results of modeling and analysis of ionospheric parameters during disturbed geomagnetic field are presented. Hourly and 15-min data of the ionospheric critical frequency (foF2) at Paratunka site (Kamchatka, Russia, 53.0 N and 158.7 E) for the period 1968–2019 were applied. The modeling was based on ionospheric parameter multicomponent model developed by the authors. In order to refine model parameters, three classes of anomalies were introduced. They characterize strong, moderate and weak ionospheric disturbances. On the basis of the modeling, we detected short-period ionospheric disturbances of moderate and weak intensity, preceding magnetic storms. They characterize occurrences of oscillatory processes in the ionosphere at the background of increased solar activity. Comparisons with the International Reference Ionosphere model (IRI-2016) and the median method were made. That showed the efficiency of the proposed model. For automatic performance of the approach, computational solutions were suggested to detect and to estimate ionospheric disturbance parameters.

基于多分量模型的电离层参数建模与分析

摘要 介绍了扰动地磁场期间电离层参数的建模和分析结果。应用了 1968-2019 年期间 Paratunka 站点（俄罗斯堪察加半岛，53.0 N 和 158.7 E）电离层临界频率 (foF2) 的每小时和 15 分钟数据。该建模基于作者开发的电离层参数多分量模型。为了细化模型参数，引入了三类异常。它们表征强、中和弱电离层扰动。在建模的基础上，我们在磁暴之前检测到了中等强度和弱强度的短周期电离层扰动。它们表征了在太阳活动增加的背景下电离层中振荡过程的发生。与国际参考电离层模型 (IRI-2016) 和中值法进行了比较。这表明了所提出模型的效率。为了自动执行该方法，建议使用计算解决方案来检测和估计电离层扰动参数。
