Book Description
Periodic fluctuations in the annual temperature and density distributions based on rocket observations at heights between 30 to 90 km are presented in terms of amplitude and phase as a function of height and latitude. The phases of the semi-annual components in arctic and subarctic regions are markedly different at levels in the upper stratosphere if the analyses are based on monthly medians rather than monthly means. Means and medians are considerably different at these altitudes during the winter months in this region due to stratospheric and mesospheric warmings.

Book Description
Fluctuations and periodic oscillations of the thermodynamic properties of the atmosphere between 25 and 80 km are analyzed in this paper to better define the structure of the tropical atmosphere. The nature of temperature and density variations at locations between 22 degrees N and 8 degrees S is examined by means of harmonic analysis. Amplitudes and phases of the annual and semiannual components of the temperature and density cycles indicate that the meteorological equator within the stratosphere and lower mesosphere lies south of Ascension Island. The paper is only one part of a larger investigation aimed at providing a set of mean monthly atmospheric models from the surface to 90 km at 15 degrees latitude intervals between equator and pole.

Book Description
Mean monthly atmospheric models are presented which depict the periodic variations in the vertical distributions of temperature, pressure, and density, surface to 90 km, at the equator and 15 deg N. The models are internally consistent and in agreement with available radiosonde and rocket observations of the thermodynamic properties of the tropical atmosphere. In the tropics the combined amplitudes of the annual and semiannual oscillations of density at altitudes between 25 and 80 km are approximately the same magnitude as the diurnal variations. Observed data show that the phase (time of maximum) of the annual temperature and density oscillations between 25 and 90 km is nearly identical at 8 deg S, 9 deg N, and 17 deg N, indicating that the meteorological equator for thermodynamic properties of the atmosphere is 8 to 10 deg south of the geographical equator.

Book Description
Interest in the meteorology of the stratosphere and mesophere has been simulated in the past few years by concerns over possible depletion of the ozone layer as a result of reactions involving pollutants introduced by human activities. Concurrently there has been an upsurge in research on various aspects of the meteorology of the stratosphere. This monograph provides an account of the fundamental dynamical processes which control the general circulation of the stratosphere and mesophere and are thus responsible for the transport of trace substances in that region of the atmosphere. Principles necessary for understanding the dynamics of large-scale motions in the stratosphere and mesosphere are systematically developed so that this monograph should prove useful not only as a reference work for research scientists, but as a textbook for courses in dynamic meteorology of the upper atmosphere.
