Coupling between atmospheric layers in gaseous giant planets due to lightning-generated electromagnetic pulses

©2014. American Geophysical Union. All Rights Reserved. Atmospheric electricity has been detected in all gaseous giants of our solar system and is therefore likely present also in extrasolar planets. Building upon measurements from Saturn and Jupiter, we investigate how the electromagnetic pulse emi...
