WebThe Earth's ionosphere has a major role in the flow of currents and energy within the magnetosphere, or what is also known as the “geospace environment”. The currents in the ionosphere are responsible for geomagnetic effects seen at the Earth's surface, and they also have a role in the high-latitude heating of the upper atmosphere. WebModel calculations for simple, but realistic conductivity and electric field distributions show that local shifts of the ionospheric field maximum against that of the magnetic field below …

WebIn geomagnetic field: Convective electrojets …is referred to as the Pedersen conductivity, and it is usually a factor of two less than the Hall conductivity perpendicular to the electric field. Consequently, the electrojet currents are actually stronger than the north–south ionospheric currents connecting the Region 1 and Region 2 currents.
Web2 jan. 2024 · The ionosphere is a portion of the Earth's upper atmospheric layers that are bombarded by radiation from the Sun.
