Book Synopsis Variability of Atmospheric Density in the Middle Atmosphere by : Arthur J. Kantor
Download or read book Variability of Atmospheric Density in the Middle Atmosphere written by Arthur J. Kantor and published by . This book was released on 1983 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analysis of the time and space variability of density in the middle atmosphere has been developed in this report, affording a means to determine density changes that occur over distances out to 200 nmi and time periods of 1 to 72 hr. Spatial variations - The rms differences between densities at locations 50, 100, and 200 nmi apart are provided in Tables 4, 8 and 11 for low- and middle- latitude stations at altitudes from 20 through 60 km. These rms values are estimates of the day-to-day variability around the mean density gradients given in Table 5 for low latitudes and Tables 9 and 12 for middle latitudes. Time variations - The rms variability of density for time periods from 1 to 12 hr in tropical regions is given in Table 13 for altitudes up to 60 km. Estimates were derived using autocorrelation theory and an analysis of the diurnal variation of density, which is the dominant periodic cycle at low latitudes. Analyses of available density observations at several midlatitude locations for altitudes between 30 and 60 km provide reasonable estimates of the magnitude (and changes with season and latitude) of the variability of density with time for periods up to 72 hr. Variations of density at these latitudes are relatively small during summer and do not increase significantly with time. Rms variations remain between 1-1/2 and 4 percent for all periods up to 72 hr.

Book excerpt: PAGEOPH, stratosphere, these differences provide us with new evidence, interpretation of which can materially help to advance our understanding of stratospheric dynamics in general. It is now weil established that smaller-scale motions-in particular gravity waves and turbulence-are of fundamental importance in the general circulation of the mesosphere; they seem to be similarly, if less spectacularly, significant in the troposphere, and probably also in the stratosphere. Our understanding of these motions, their effects on the mean circulation and their mutual interactions is progressing rapidly, as is weil illustrated by the papers in this issue; there are reports of observational studies, especially with new instruments such as the Japanese MV radar, reviews of the state of theory, a laboratory study and an analysis of gravity waves and their effects in the high resolution "SKYHI" general circulation model. There are good reasons to suspect that gravity waves may be of crucial significance in making the stratospheric circulation the way it is (modeling experience being one suggestive piece of evidence for this). Direct observational proof has thus far been prevented by the difficulty of making observations of such scales of motion in this region; in one study reported here, falling sphere observations are used to obtain information on the structure and intensity of waves in the upper stratosphere.
Book Synopsis The Earth's Middle Atmosphere by : W. L. Grose
Download or read book The Earth's Middle Atmosphere written by W. L. Grose and published by Elsevier. This book was released on 2016-06-06 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Earth’s Middle Atmosphere covers the Proceedings of Symposium C2 and the Topical Meetings of the COSPAR Interdisciplinary Scientific Commissions A and C (Meetings A7 and C4) of the COSPAR 29th Plenary Meeting held in Washington, DC, USA, on August 28-September 5, 1992. The first part covers the impact of the Upper Atmosphere Research Satellite (UARS) observations on middle atmosphere science. This topic includes the early results of the validation and the application of the Cryogenic Limb Array Etalon Spectrometer (CLAES) data, which is an instrumental approach to the measurement of thermal infrared spectral emission from the atmospheric limb. An overview of the Halogen Occultation Experiment and the use of the UARS data in the NOAA stratospheric monitoring are also discussed in this part. It also includes the observed solar UV irradiance variations of importance to middle atmosphere energetic and photochemistry, as well as the stratospheric and mesospheric observations with the Improved Stratospheric and Mesospheric Sounder. The second part of the book tackles the energetics and chemistry of the middle atmosphere as well as the dynamics and coupling of the middle atmosphere to regions above and below. Results on the validation of the UARS wind and temperature measurements at and above the mesopause comprise the third part of this book. This book will be a great value to geophysicists and atmospheric scientists.

Book Synopsis The Atmosphere and Climate of Mars by : Robert M. Haberle
Download or read book The Atmosphere and Climate of Mars written by Robert M. Haberle and published by Cambridge University Press. This book was released on 2017-06-29 with total page 613 pages. Available in PDF, EPUB and Kindle. Book excerpt: Humanity has long been fascinated by the planet Mars. Was its climate ever conducive to life? What is the atmosphere like today and why did it change so dramatically over time? Eleven spacecraft have successfully flown to Mars since the Viking mission of the 1970s and early 1980s. These orbiters, landers and rovers have generated vast amounts of data that now span a Martian decade (roughly eighteen years). This new volume brings together the many new ideas about the atmosphere and climate system that have emerged, including the complex interplay of the volatile and dust cycles, the atmosphere-surface interactions that connect them over time, and the diversity of the planet's environment and its complex history. Including tutorials and explanations of complicated ideas, students, researchers and non-specialists alike are able to use this resource to gain a thorough and up-to-date understanding of this most Earth-like of planetary neighbours.
Book Synopsis Aeronomy of the Middle Atmosphere by : G. Brasseur
Download or read book Aeronomy of the Middle Atmosphere written by G. Brasseur and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: The reader may be surprised to learn that the word "aeronomy" is not found in many of the standard dictionaries of the English language (for exam ple, Webster's International dictionary). Yet the term would appear to exist, as evidenced by the affiliations of the two authors of this volume (Institut d' Aeronomie Spatiale, Brussels, Belgium; Aeronomy Laboratory, National Oceanic and Atmospheric Administration, Boulder, CO, USA). Perhaps part of this obscurity arises because aeronomy is a relatively new and evolving field of endeavor, with a history dating back no farther than about 1940. The Chambers dictionary of science and technology provides the following defini tion: "aeronomy (Meteor. ). The branch of science dealing with the atmo sphere of the Earth and the other planets with reference to their chemi cal composition, physical properties, relative motion, and reactions to radiation from outer space" This seems to us an appropriate description, and it is reflected throughout the content of this volume. The study of the aeronomy of the middle atmosphere experienced rapid growth and development during the 1970's and 1980's, particularly due to con cern over the possibility of anthropogenic perturbations to the state of the middle atmosphere and its protective ozone layer. As a result, much has been learned regarding both the natural behavior of the atmosphere and the impact of man's activities upon it. In this book we shall attempt to describe the current state of the art as we see it.

Book excerpt: The 80 to 130 km altitude region is our old 'ionosphere' - the region of the atmosphere that no one seems to be interested in, and yet the critical region for shuttle entry and atmospheric braking. Comparison between the Air Force reference atmosphere and Shuttle IMU data shows large fluctuations at high latitudes. New data sources are available new, such as the Arecibo and Millstone Hill ionospheric scatter radars. (Author).

Book Synopsis Variations with Season and Latitude of Density, Temperature, and Composition in the Lower Thermosphere by : K. S. W. Champion
Download or read book Variations with Season and Latitude of Density, Temperature, and Composition in the Lower Thermosphere written by K. S. W. Champion and published by . This book was released on 1967 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analysis of neutral density data has made it possible to extend curves of mean density as a function of latitude and season from 90 to 120 km. There is an approximate isopycnic point at 91 km. Above this point the density variations are reversed from what they are at 80 km. In other words, at 120 km the density in summer and at the tropics is lower than that in CIRA 1965 and in winter the density is higher. The density curves have been idealized near 120 km to join at one of three points. These correspond to typical summer and tropical conditions, winter conditions, and spring/autumn conditions. The summer density is 20 percent below that of the U.S. Standard, the winter density is 50 percent above the Standard and the spring/autumn density is 1 percent above the Standard. By application of appropriate theory the corresponding variations in temperature and mean molecular weight have been calculated. An unexpected result of the theory is the prediction of a seasonal variation of the mean molecular weight. Some of the data presented in the paper have been analyzed since the models were derived. These data have been found to be acceptably close to the models. (Author).
