The report surveys the significance of fluid dynamical motions in the terrestrial thermosphere, placing emphasis on important problems that are as yet unsolved. When the need of interpreting certain important new atmospheric phenomena arises, the author attempts to develop new theories, using, if possible, the simplest mathematical methods, or even dimensional arguments. In this connection, theories are developed on the following the minimum scales of gravity waves, the spectrum of gravity turbulence, the spectrum of shear turbulence, and the turbulent diffusion and anomalous distribution of oxygen in the atmosphere.
