The growth rate of the geodesic acoustic mode and the radial structures of the sideband drift waves and the geodesic acoustic modes continuum are studied as a paramet- ric process in the tokamak plasmas with a non-uniform ion temperature profil for which the non-uniform part of the inherent geodesic acoustic mode frequency takes the form of tanh function. It is shown that the radial structures of the drift wave sideband are close to the harmonic function, the energies of the geodesic acoustic modes the resonant points of the parametric excitations square of the amplitude of the pump wave are m...
