Analysis of High-Latitude lonospheric Processes During HSS and CME-Induced Geomagnetic Storms
For the first time we compared ionospheric effects of HSS and CME-driven storms at high-latitudes. There were similarities and also differences observed in the development of the storms. (1) Both type of storms exhibited clear negative phase, which resulted in an increase of TOI-breaking-down into p...
