Abstract
Three nonlinear Alfvén wave phenomena in the planetary magnetosphere are discussed: (1) magnetohydrodynamic parametric instabilities induced by a nonlinear standing Alfvén wave, (2) parametric excitation of Alfvén and Langmuir waves by a nonlinear electromagnetic whistler wave, and (3) parametric generation of electromagnetic waves in the vicinity of electron plasma frequency via nonlinear coupling of Langmuir and Alfvén waves. Observational evidence in support of these nonlinear Alfvén wave phenomena, such as the auroral Alfvén-acoustic turbulence and the auroral Langmuir-Alfvén-whistler (LAW) events, in the planetary magnetosphere is presented.
