Amplification of whistler waves for the precipitation of trapped relativistic electrons in the magnetosphere

Summary form only given, as follows. In the magnetosphere, energetic electrons in the radiation belts are trapped by the Earth´s dipole magnetic field and undergo bouncing motion about the geomagnetic equator. Induced electron precipitation into the ionosphere and upper atmosphere by whistler waves has been observed. Whistler waves in the magnetosphere can be excited during lightning events or launched into the magnetosphere by the ground or or space-based VLF transmitters. In the present work, the trajectories of these trapped energetic electrons interacting with a large amplitude whistler wave are examined.
