电离层异常原因分析与建模

摘要

This paper analyzes the physical mechanism of ionospheric anomalies caused by natural phenomena such as earthquakes , storms, solar flares and summarizes the characteristics of ionospheric anomalies .For the phenomenon that the electron distribution in the ionosphere is greatly affected by geomagnetic , solar heat radiation and changes in the earth's crust, based on the parabolic layers and equatorial bimodal model , the ionosphere anomalies model that the electron density is Gaussian distribution is established to pro -vide a basis for further study on the coupling mechanism of the ionosphere anomalies .%分析了地震、磁暴、太阳耀斑等自然现象引发电离层异常的物理机制，并总结了电离层异常的特点。针对电离层中电子分布受地磁、太阳热辐射和地壳变动等影响较大，基于抛物层和赤道双峰模型建立了电子密度呈高斯型分布的电离层异常模型，为进一步研究电离层异常的耦合机制提供了依据。
