Interpretive Studies of Ionospheric Electrodynamics

本研究旨在探讨植物群落的形成、演化和 电离层中间层的电动力学后果。 这些离子浓度增强的区域出现在 夜间F区域的底侧可以通过以下动作形成： 重力波中性风场 作为现在毕业生的一部分 学生项目的非ExB运动的电离层等离子体在 高度低于约200公里已成功纳入。 这一物理现象被添加到以前的电离层模型中， 假设通量管上的所有血浆仅受ExB影响 垂直于磁场漂移。 由于这种 工作可以对形成进行检查 中间层被认为是形成的结果， 重力波中性风场的作用。 在这项提案中， 传播中性风场产生扰动的能力 在周围电离层剖面中的作用， 金属离子可能在这些层的外观中起作用， 高度将被检查。

This proposal is for studying the formation, evolution and electrodynamic consequences of ionospheric intermediate layers. These regions of enhanced ion concentration that appear in the bottomside of the nighttime F region can be formed by the action of gravity wave neutral wind fields. As part of a present graduate student project the non-ExB motion of the ionospheric plasma at altitudes below about 200 km has been successfully incorporated. This physics was added to the previous ionosphere model which assumed all the plasma on a flux tube was subject only to ExB drifts perpendicular to the magnetic field. As a result of this work it is possible to undertake an examination of the formation of intermediate layers that are thought to form as a result of the action of gravity wave neutral wind fields. In this proposal the ability of propagating neutral wind fields to produce perturbations in the ambient ionospheric profile and the role that non-reactive metallic ions might play in the appearance of these layers at lower altitudes will be examined.
