Ionospheric electric current

Japanese: 電離圏電流 - でんりけんでんりゅう(英語表記)ionospheric electric current
Ionospheric electric current
In the ionosphere, atmospheric molecules and atoms coexist with ions and electrons (free electrons) produced by ionization, and when an electromotive force such as an electric field is generated in the ionosphere, the ions and electrons move, causing a flow of charge, or electric current. This is why the ionosphere is electrically conductive. The existence of electrically conductive regions in the Earth's upper atmosphere was suggested in 1878 by Stuart B. Stewart as the cause of the daily geomagnetic variation, and in 1902 by A.E. Kennelly and O. Heaviside as a reflector layer for radio waves.

Japanese:
電離圏には大気の分子・原子とともに電離によって生じたイオンや電子(自由電子)が共存しており,電離圏に電場などの起電力が発生すると,イオンや電子が運動するため電荷の流れすなわち電流が生じる。電離圏は電気伝導性をもっているわけである。地球の上層大気中に電気伝導領域が存在することは,1878年にスチュアートB.Stewartが地磁気日変化の原因として示唆しており,1902年にはA.E.ケネリーとO.ヘビサイドが電波の反射層として示唆している。
