Abstract
Protons, electrons, alpha particles, and heavier ions in the solar wind are emitted from the Sun’s coronal plasma. Energetic phenomenon such as a Coronal Mass Ejection (CME) releases high energy as electromagnetic radiation in the form of solar X-rays and γ-ray bursts. This intense radiation is responsible for ionizing the constituent particles of the various layers of Earth’s ionosphere. In the presence of perturbations of the thermospheric region produced by CME, different characteristic parameters are theoretically investigated through momentum and energy balance equations, equation of continuity and equation of state. Dispersive nature of the medium is investigated and altitude variations of resulting electric field are carried out. In the computation processes, data of the latest International Reference Ionosphere (IRI) models are used. The results obtained are to be compared and supported by the experimental findings from other researchers to understand the nature of the medium in detail.
