The continuity equation of electron density is solved to yield an expression for the vertical transport, which can be evaluated from electron- density, true-height profiles. A few numerical computations are presented for the vertical drift velocities determined for stations at Huancayo, Talara, Panama, and Washington, D. C. It is shown that the velocity is predominantly downward during the night and upward during the day at the equatorial stations. There is an apparrent phase reversal from summer to winter at Washington, The order of vertical velocity amplitude is 25 m/sec. The dynamical equations are derived for the conditions existing in the upper atmosphere, and their solutions are obtained making some appropriate assumptions. It is shown that the semi- diurnal oscillation of the atmosphere is caused by a Coriolis resonance and is independent of any physical-property of the atmosphere. A few computations are made for the velocity of electrons using pressure and density data obtained from satellite experiments. The result is in agreement only to an order of magnitude with the values obtained from N-h profties. (Dissertation Abstr., 22: No. 7, 1982.)
