No One Can Walk Out From His/Her Own Story
Space weather refers to the solar wind, Earth's magnetosphere, ionosphere, and thermosphere conditions, as well as the near-Earth space environment that affects the reliability and efficiency of both space-based and ground-based technological equipment. Coronal mass ejections (CMEs) and high-velocity solar wind produced by the sun could be the cause of unusual space weather conditions. The magnetosphere of Earth is affected by high-speed solar wind and CMEs, by releasing energy into the high-latitude ionosphere through magnetospheric field-aligned currents (FACs), these solar wind and CME interactions have the potential to cause unstable disruptions in the high-latitude ionosphere. High-latitude disturbances spread toward the equator in the form of neutral winds, electric fields, etc., and modify ionospheric electrodynamics. Modifications in ionospheric electrodynamics affect space and ground-based technological systems such as navigation and communications systems, satellite performances and reliability, the efficiency of electric powers, etc. As we are becoming more and more dependent on space-based technologies, it is essential to understand the changing space weather conditions and their impacts on technological systems.
