Abstract The paper deals with the problem of the equatorial ionization anomaly (EIA) modelling and its representation in the global dynamical models of Earth’s ionosphere and thermosphere. A new version of the coupled thermosphere-ionosphere global dynamical model which reproduce the equatorial anomaly considerably well is presented. Key processes responsible for the EIA formation are outlined and their representation in the model is indicated. It was shown that the developed coupled thermosphere-ionosphere model with additional accounting of vertical electromagnetic drift at the equator realistically represents the EIA characteristics.

在 INM RAS 耦合热层-电离层模型中对赤道电离层异常进行建模

摘要 本文讨论了赤道电离异常（EIA）建模问题及其在地球电离层和热层的全球动力学模型中的表示。提出了一种新版本的耦合热层-电离层全球动力学模型，该模型可以很好地再现赤道异常。概述了负责 EIA 形成的关键过程，并指出了它们在模型中的表示。结果表明，开发的热层-电离层耦合模型加上赤道垂直电磁漂移的额外计算真实地代表了 EIA 特征。
