Dynamics of the Thermosphere During Quiet and Disturbed Conditions external forcing. A simplified theory of the propagation and generation of acoustic-gravity waves and of planetary waves is outlined using the linearization of the hydrodynamic equations and the superposition of harmonic waves via a Fourier series of a Fourier integral. The main energy sources at t

Wind Induced Composition Effects at High Latitudesectively transport the lighter and minor species from the warmer toward the cooler regions on the globe. Due to the abundance of atomic oxygen a back pressure develops which significantly dampens the wind velocities and increases the temperature contrast. During summer and under magnetically disturb

Radio Observations of the Auroral F-Regionave been made by means of ground based and satellite borne ionosondes respectively. From these data, the basic features and behaviour of the region have been determined. In recent years new techniques, such as incoherent scatter radar, have added to our knowledge, particularly regarding transient be

Polar Cap Optical Emissions Observed from the ISIS2 Satellitelar cap processes. The ISIS2 satellite, which is in a circular orbit 1400 km above the earth’s surface, has provided monochromatic optical images of the high latitude region since April 1971. The 5577? emission from atomic oxygen and the 3914 ? emission from the First Negative bands of N.. have been

Optical Emissions in the Polar Auroral E-Region molecular oxygen emissions in the airglow require a peak atomic oxygen concentration of about 1.E12 cm-3*. It is suggested that these emissions are excited in a two step process similar to the Barth mechanism for the green line. It is proposed that monitoring of the green line and the atmospheric b
