This project centers on use of the Rice Convection Model (RCM) to study the Earth's magnetosphere and its coupling to the ionosphere and thermosphere. Computer experiments based in interactively combining the RCM with numerical models of the thermosphere should allow determination of whether thermospheric winds can substantially affect the injection of the magnetosphere's storm-time ring current. Combined magnetosphere-ionosphere-thermosphere simulations will also be directed at the dynamic behavior of the low-mid-latitude ionospheric electric fields, which move the ionospheric F-layer and affect its structure. Utilizing newly developed computational machinery for representation of radiation-belt particles, field-aligned potential drops, charge exchange with neutrals, auroral precipitation, and substorm-associated collapse of the magnetotail magnetic field, computer experiments with the RCM will probe the effects of these processes on basic magnetospheric phenomena, particularly substorms and storms.

该项目的重点是使用莱斯对流模型（RCM）来研究地球磁层及其与电离层和热层的耦合。 基于将 RCM 与热层数值模型交互结合的计算机实验应该能够确定热层风是否会显着影响磁层风暴时环流的注入。 磁层-电离层-热层组合模拟还将针对低中纬度电离层电场的动态行为，该电场移动电离层F层并影响其结构。 利用新开发的计算机械来表示辐射带粒子、场对准电势降、与中性粒子的电荷交换、极光降水以及与亚暴相关的磁尾磁场崩溃，RCM 计算机实验将探讨这些过程对基本磁层现象（特别是亚暴和风暴）的影响。
