Abstract

A mechanism associated with the filamentation instabilities of circularly polarized waves is investigated, showing the capability of producing significantly large earth magnetic field fluctuations in addition to ionospheric density fluctuations. This mechanism is suggested as the cause of earth magnetic field fluctuations reported by Stubbe and Kopka (1981) in the ionospheric heating experiments performed at the EISCAT facilities in Tromso, Norway.
