Description
The Earth's ionosphere and thermosphere are strongly influenced by forcing through the solar windmagnetosphere interaction. During geomagnetic storms, strong electric fields and currents are transmitted between the high-latitude ionosphere, and enhanced particle precipitation occurs along the auroral oval. The conductivity of the ionosphere increases, neutral winds are accelerated, and the thermosphere is heated, its composition is modified, and plasma and neutral gases are redistributed. In this paper we discuss the effects of the different processes on the ionosphere and thermosphere using the coupled AMIE-TIMEGCM. Observational and modeling results from selected geomagnetic storm events will be shown to illustrate the complex response of the ionosphere and thermosphere to various solar and magnetospheric forcing.
