Vertical coupling and transport in high-latitude ionosphere
Various ionospheric plasma anomalies appear at auroral latitudes, extending across the polar cap as a tongue of ionisation (TOI) and/or polar patches (PPs). Mechanisms responsible for horizontal and vertical plasma transport include the forcing from above (solar irradiance and geomagnetic activity)...
