Description

The ionospheric response to geomagnetic storms is an important space weather phenomenon caused by solar events such as coronal mass ejections (CMEs). The ionosphere is important for long distance high frequency (HF) communication. The scientific understanding of the ionospheric response during extreme geomagnetic storm is essential in mitigating the impacts in an operational space weather environment. The presentation will provide an analysis of three major geomagnetic storms influence on the ionosphere. Various space weather parameters such as solar wind speed, IMF Bz, disturbance storm time index and ionospheric measurements will be used to evaluate the intensity of ionospheric responses over the mid-latitude region.
