Book Description
The wind in the lower thermosphere is generally considered to be composed of prevailing, tidal and gravity wave components. However the observations of the wind, primarily from meteor trail and vapor trail drifts, are available at only a few locations and in the case of vapor trail drifts, only during the night hours. Because of the heterogeneous nature of the data, it has not been possible to definitely specify the contribution of each of these components to the total wind. In an attempt to improve the interpretation of the observations, tidal winds are computed from theory. To do this, the effects of dissipation and excitation in the thermosphere must be considered. In this work, the effects of heat conductivity and the absorption of solar radiation in the thermosphere are added to the tidal theory. (Author).

Book Description
A study is made of the variation of atmospheric parameters in the lower thermosphere (80-150 km) in terms of the theory of atmospheric tides. The existing tidal theory is expanded to include the effects of dissipation and excitation in the thermosphere. The effects of heat conductivity and absorption of solar radiation in the thermosphere are added to the existing tidal theory. The results are then compared with observations of winds in the lower thermosphere to determine the extent to which the tidal theory cay explain the observed variations of meteorological variables in the lower thermosphere. Results indicate that many features of lower thermospheric wind profiles can be explained in terms of tidal theory, including the effects of dissipation and thermospheric heating. (Author).

Book Description
Everyone is familiar with the daily changes of air temperature. The barometer shows that these are accompanied by daily changes of mass distribution of the atmosphere, and consequently with daily motions of the air. In the tropics the daily pressure change is evident on the barographs; in temperate and higher latitudes it is not noticeable, being overwhelmed by cyclonic and anticyclonic pressure variations. There too, however, the daily change can be found by averaging the variations over many days; and the same process suffices to show that there is a still smaller lunar tide in the atmosphere, first sought by Laplace. Throughout nearly two centuries these 'tides', thermal and gravitational, have been extensively discussed in the periodical literature of science, although they are very minor phenomena at ground level. This monograph summarizes our present knowledge and theoretical under standing of them. It is more than twenty years since the appearance of the one previous monograph on them - by Wilkes - and nearly a decade since they were last comprehensively reviewed, by Siebert. The intervening years have seen many additions to our know ledge of the state of the upper atmosphere, and of the tides there, on the basis of measurements by radio, rockets and satellites.
