Web7 mei 2024 · The behavior of the ionospheric plasma is controlled by collisions among the ionized particles and neutrals as well as among the ionized particles themselves. It may also be driven by a geomagnetic field, where the particle density is low and consequently the collision frequency as well. WebAn ionospheric storm is a perturbation of the ionization density at F-region heights. Geomagnetic storms, being the result of a coronal mass ejection or a high-speed solar wind stream passing the Earth, are one of the main sources of ionospheric storms as solar wind energy is captured by the magnetosphere, then transformed and dissipated in the polar …
