This grant supports a study of internal energy sources of               the plasma waves in the space plasma (the magnetospheres of the                 earth and other planets) by using analytical and numerical                      methods.  The theoretical models will be developed to incorporate               realistic features of space plasma including inhomogeneities in                 density and temperature, anisotropy of the temperature, finite                  beta and larmor radius effects.  The detailed study of the                      internal energy sources of gradients, particle beams and                        nonlinear parametric processes will be carried out.  Appropriate                dispersion relations will be derived and numerically analyzed to                obtain wave frequency, growth rates and threshold limits.  The                  model generated wave parameters will be compared with the                       observations.                                                                           The importance of geophysical low frequency waves is the                interpretation of geomagnetic pulsations (micropulsations) as low               frequency hydromagnetic waves originating in the magnetosphere.                 Thus the waves become a tool for the study of the near earth                    plasma density.  Furthermore, the study of the waves provide an                 opportunity to elucidate basic processes not readily available in               the laboratory.
