Title: Geomagnetic pulsation generation as a result of whistler wave scattering

Abstract

Nonlinear scattering of whistler mode waves by kinetic Alfv{acute e}n waves (KAWs) is considered. The evolution of whistler mode wave decay instability in time and two spatial dimensions is studied under the approximation of two-fluid magnetohydrodynamics. It is shown that efficient coupling between whistler waves and KAWs is possible due to the finite Larmor radius effect for Alfv{acute e}n waves. The considered process can lead to significant enhancement of KAWs. The nonlinear scattering of whistler waves by KAWs is proposed as a possible mechanism of enhancement and generation of geomagnetic pulsations in the magnetosphere and ionosphere of the Earth. {copyright} {ital 1999 American Institute of Physics.}
