A comprehensive theoretical analysis was carried out on the generation of hydromagnetic Alfven waves in a realistic magnetospheric plasma environment consisting of a core (about 100 eV) component and an energetic (about 10 keV) component. The theoretical formulation employs the gyrokinetic equations and, thus, retains anisotropy, finite Larmor radii, magnetic trapping, and wave-particle interactions in addition to nonuniform plasma equilibria. A set of coupled equations for transverse and compressional magnetic perturbations is derived and analyzed for its stabilities assuming equilibrium distribution functions which are interchange stable. It is found that compressional and transverse shear Alfven oscillations are generally coupled in realistic plasmas, and, in the decoupled limit for the compressional wave branch, the drift mirror instability due to the Landau resonances is recovered.
