Interpretive Studies of Ionospheric Electrodynamics

这一提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域可能是由重力波中性风场的作用形成的。作为当前研究生项目的一部分，电离层等离子体在海拔约200公里以下的非exb运动已经成功地纳入其中。这一物理现象被添加到先前的电离层模型中，该模型假设磁通管上的所有等离子体只受垂直于磁场的ExB漂移的影响。由于这项工作，有可能对中间层的形成进行检查，中间层被认为是由于重力波中性风场的作用而形成的。在本提案中，将研究传播中性风场在环境电离层剖面中产生扰动的能力，以及非活性金属离子在较低海拔地区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.
