Parametric interactions of whistler mode waves and lower-hybrid resonance waves in the upper ionosphere and magnetosphere

We review the theory, as well as satellite and ground-based data testifying to the high efficiency of parametric interactions of whistler mode waves and lower-hybrid resonance (LHR) and ion-acoustic or ion-cyclotron waves. Some applications of the parametric effects to diagnostics of the ionosphere and the magnetosphere are discussed.
