Saturation of Alfven oscillations in the ring current region due to generation of lower hybrid waves

The possibility of flux generation of lower hybrid oscillations in the ring current region of the Earth's magnetosphere is suggested in this paper. The energy level of lower hybrid oscillations can exceed the modulational instability threshold, which leads to the formation of caverns. The consequences of this are qualitatively analysed. Also, an assumption is made that the flux instability of lower hybrid oscillations may limit the level of Alfven oscillations in the ring current region.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/30137/1/0000514.pd
