Upper Atmosphere Studies

Abstract

The Earth’s atmosphere occupies some million times greater volume than the solid Earth. In this huge system, the charged plasma particles react strongly to electric and magnetic fields. Hence, electrical processes in one part of the system can influence the electrodynamical processes in another distant part. The redistribution of the charged particles in turn can modify the existing electric and magnetic fields in the atmosphere. Hence, an investigation of electrodynamical processes in various regions of the atmosphere and their coupling is very important for understanding the state of electrical environment of the Earth’s atmosphere.
