Interpretive Studies of Ionospheric Electrodynamics

这一建议是为了研究电离层中间层的形成、演化和电动力学后果。这些出现在夜间F区底部的离子浓度增强区可以由重力波中性风场的作用形成。作为目前一个研究生项目的一部分，已经成功地纳入了电离层等离子体在海拔约200公里以下的非EXB运动。这一物理被添加到以前的电离层模型中，该模型假设通量管上的所有等离子体只受垂直于磁场的Exb漂移的影响。作为这项工作的结果，有可能对中间层的形成进行检查，这些中间层被认为是由于重力波中性风场的作用而形成的。在这项提议中，将审查传播中性风场在周围电离层轮廓中产生扰动的能力，以及非反应性金属离子在低海拔这些层的出现中可能发挥的作用。

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.
