This stomp phenomena is simplot near the Poles due to the vertical direction of magnetic field lines.

The colours of the auroras displayed on the nature of chemical interactions with different gases lie the oxygen, nitrogen en. Uses to influence in radio, satellite signals en - impacts communication en earth. Haga Affects space weather in the atmosphere - especially for satellites, Auroras in the lower earth orbit. Hag lead to heeing of atmosphere - ionization of plume gases in thermosphere.
