UPPER ATMOSPHERE DYNAMICAL MOTIONS WITH SPECIAL CONSIDERATION OF THE CORIOLIS FORCE AND INCLUDING THE EFFECTS OF ELECTRIC FIELDS
Abstract
The dynamical equations have been set up for the conditions existing in the upper atmosphere and their solutions have been obtained making some appropriate assumptions. It is shown that the semi-diurnal oscillation of the atmosphere is due to a Coriolis resonance and is independent of any physical property of the atmosphere. It is further shown how the pressure and density data can be used to compute the velocity of the neutral particles. The velocities of ions and electrons have been expressed in terms of the neutral particle velocity, the collision frequencies and the electric field. Using Maxwell's equations and the solution of the dynamical equations, a differential equation for electric field has been obtained containing the velocity of the neutral particles and collision frequencies. It is shown how the pressure, density and collision frequency data may be used to compute the velocities of neutral particles, electrons and ions, also the electric field. (Author)
