Relationship between electron-density variations in the midlatitude lower ionosphere and ring-current intensity
Abstract
The variation of electron density in the midlatitude D-region is analyzed as a function of Dst and Kp indexes. It is shown that, for solar zenith angles ranging from 65 to 80 deg, there exists a significant negative correlation between electron density and Dst, this correlation becoming weaker as Kp increases.
