Abstract : The report is divided into three parts: The presence of large scale time-dependent dynamic disturbance in the ionosphere may be treated by using an inhomogeneous linear integral equation with Green's function satisfying homogeneous boundary conditions. For the special case where there is no disturbance, the theory reduces to the well known results for a quiet ionosphere. The disturbance of the ionosphere by a long period travelling wave originating in the northern hemisphere has been detected in the southern hemisphere with the accompanying expected phase change as the wave crosses the magnetic equation. A comprehensive survey has been made into the question of anomalous sounds from auroras. Preliminary results seem to show that the theory of brush discharge can properly explain all the observed phenomena without inconsistency. (Author)
