Abstract : POWER SERIES, PERUNUMERICAL INTEGRATION, GRAVITY WAVES, INFRASONICS, RADIATION, *THERMOSPHERETwo studies of the thermospheric physics and dynamics are considered. In the first study a comprehensive theoretical discussion of the nature of energy sources and of the general theory of gravity-tidal wave motions in the neutral gas is given. Motions which are of planetary scale in the horizontal and which have time scales of order of a day or longer are considered. in the second study the 'thermal geoplasma motion regime' forced by solar heating and infrared cooling is integrated numerically in the forced region and analytically outside the forced region. The analytical study reduces to the solution of a fourth order ordinary differential equation whose solutions are coefficients of spherical harmonics. Power series solutions satisfying the condition of no flux at z = infinity are obtained. (Modified author abstract)
