This book was released on 1965 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mean pressure patterns in the middle stratosphere and the latitudinal distribution of total ozone are presented for both hemispheres. It is then inferred that the major stratospheric warmings are probably associated with non-linear baroclinic interaction between troposphere and stratosphere. The major difficulties in resolving the problem arise from the absence of vertical motion measurements and our present inability to model effectively on the planetary scale. (Author).

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.
Download or read book Some Features of Air Density Profiles Up to the Middle Stratosphere written by Werner H. Alfuth and published by . This book was released on 1961 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: Per cent deviations of air density from the ARDC Model Atmosphere 1956 are presented for the following locations: Grand Bahama Island, West Indies; Patrick AFB, Florida; Tokyo-Haneda, Japan; International Falls, Minnesota; and Fairbanks, Alaska. Since frequency distributions of air density are often not normal, a mere presentation of formally computed statistics, such as, means and standard deviations has been omitted. Rather the levels of 0.15 per cent, 50 per cent, and 99.85 per cent cumulative percentage frequency were selected to represent median and 'extreme' conditions. The latitudinal and seasonal variations of air density in the different altitude layers are discussed. A separate section has been added under the heading 'Conclusions' to provide a summary of the essential findings. (Author).
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.

Download or read book Stratosphere Troposphere Interactions written by K. Mohanakumar and published by Springer Science & Business Media. This book was released on 2008-07-03 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stratospheric processes play a signi?cant role in regulating the weather and c- mate of the Earth system. Solar radiation, which is the primary source of energy for the tropospheric weather systems, is absorbed by ozone when it passes through the stratosphere, thereby modulating the solar-forcing energy reaching into the t- posphere. The concentrations of the radiatively sensitive greenhouse gases present in the lower atmosphere, such as water vapor, carbon dioxide, and ozone, control the radiation balance of the atmosphere by the two-way interaction between the stratosphere and troposphere. The stratosphere is the transition region which interacts with the weather s- tems in the lower atmosphere and the richly ionized upper atmosphere. Therefore, this part of the atmosphere provides a long list of challenging scienti?c problems of basic nature involving its thermal structure, energetics, composition, dynamics, chemistry, and modeling. The lower stratosphere is very much linked dynamically, radiatively,and chemically with the upper troposphere,even though the temperature characteristics of these regions are different. The stratosphere is a region of high stability, rich in ozone and poor in water - por and temperature increases with altitude. The lower stratospheric ozone absorbs the harmful ultraviolet (UV) radiation from the sun and protects life on the Earth. On the other hand, the troposphere has high concentrations of water vapor, is low in ozone, and temperature decreases with altitude. The convective activity is more in the troposphere than in the stratosphere.

Scientific Affairs Division and published by Springer Science & Business Media. This book was released on 1997-10-10 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive introduction to the stratosphere and its role in our understanding of the climate system. The key dynamic, radiative, and chemical processes that determine the distribution of chemical compounds including ozone in the stratosphere are discussed. The chapters contributed by outstanding experts focus not only on fundamental aspects related to these issues, but also present a number of applications including instrumentation, laboratory studies, and atmospheric observations.
Download or read book Stratospheric Ozone Depletion and Climate Change written by Rolf Müller (physicien.) and published by Royal Society of Chemistry. This book was released on 2012 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, several new concepts have emerged in the field of stratospheric ozone depletion, creating a need for a concise in-depth publication covering the ozone-climate issue. This monograph fills that void in the literature and gives detailed treatment of recent advances in the field of stratospheric ozone depletion. It puts particular emphasis on the coupling between changes in the ozone layer and atmospheric change caused by a changing climate. The book, written by leading experts in the field, brings the reader the most recent research in this area and fills the gap between advanced textbooks and assessments.
