Abstract

AbstractObservations show that whistler waves play a very crucial role both in magnetic reconnection and turbulence. In this context, linear and nonlinear dynamical equations of whistler wave have been derived and further these equations have been solved numerically as well as semianalytically. For application purpose, magnetotail parameters have been chosen. The obtained results reveal that the nonlinearity as well as field perturbation results in the formation of localized structures. These structures contribute to the turbulence and lead to the formation of current sheets in the magnetotail. Finally, the power spectrum has been evaluated and compared with the observed spectra in the magnetotail ion diffusion region as reported.
