Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 87. This volume provides a review of progress made in recent years in experimental and theoretical investigation of the upper mesosphere and lower thermosphere and coupling between these regions and the ionosphere. Detailed study of the mesosphere/lower thermosphere/ionosphere (MLTI) region has historically been difficult because of its relative inaccessibility to direct measurement techniques and the complex and highly coupled processes which occur there. Although we have still not successfully unraveled all these complex interactions, we have made significant recent progress toward a fuller understanding of the basic state of the MLTI and of the dominant wave and coupling processes. This monograph includes a set of tutorial papers, which review our current understanding of aspects of the MLTI. These tutorials are interspersed with a selection of papers describing research progress on various topics of current interest in this region. The book should therefore be useful both to the newcomer, as an introduction to this field of research, and to the more experienced researcher, providing an overview of research in progress as well as a convenient reference collection of papers describing our current understanding.
Ground-based Optical Detection of Atmospheric Waves in the Upper Mesosphere and Lower Thermosphere
Figure 2.6a shows the latitude versus months cross sections of the DE3 amplitudes at altitudes of 80 km (bottom plot) and 105 km (upper plot), representing the tidal features in the mesosphere and lower thermosphere, respectively.

More recently, Batten (1961) has prepared a cross section of zonal winds similar to Fig. 3.2. His results suggest that the summer wind maximum near the stratopause should be somewhat lower in altitude and farther south than shown WINTER ...
