A Model of the Auroral Electrojet Dynamics Based on Planetary K-Index

The solar wind-magnetosphere coupling and the magnetosphere-ionosphere coupling form a current system, also known as an electrojet. The current system formed in the auroral regions during the main phase of geomagnetic storms is a phenomenon called auroral electrojet. In this research, the number density, temperature, and velocity of the auroral electrojet electrons were calculated theoretically by relating them to the Planetary K-index, a measure of the disturbance in the Earth’s magnetic field.
