Available in PDF, EPUB and Kindle. Book excerpt: Some preliminary analysis are presented of the winds and circulations in the mesosphere based upon the first year of data collected by the Meteorological Rocket Network.

T er atmosphere, Meteorological data, *Sounding rockets, Diurnal variations, North America, *Wind. Open-ended Terms: Mesosphere. Some preliminary analysis are presented of the winds and circulations in the mesosphere based upon the first year of data collected by the Meteorological Rocket Network. Differences between winds determined from radar targets released by rockets and those from the conventional balloon technique are discussed briefly. The scale of seasonal, daily, and vertical wind variations is illustrated by wind profiles and time cross-sections. They demonstrate clearly the seasonal reversal of mesospheric winds and the existence of large, wind-speed variations over periods of only several days. They also reveal that vertical wind shears of 0.030 per sec, and probably greater, exist at about 180,000 ft. A relationship is indicated between mesospheric circulation changes and subsequent tropospheric circulation changes. Examples are shown of the circulation over North America in spring and summer at heights up to 180,000 ft. Analysis of rocket wind-data indicates that the techniques are sound and that much can be learned by more intensive analysis. (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.

This book was released on 1972 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Meteorological soundings of the upper stratosphere and mesosphere, conducted with in situ rocket techniques during all seasons of the year from several sites, ranging in latitude from 8 deg S to 71 deg N, are analyzed. The resulting data are compiled into mean monthly and seasonal profiles of temperature, pressure, density, and wind for each site and are presented in graphical and tabular form. Analyses of these mean values produced time cross sections, quasi-meridional cross sections, and constant level maps which are included."--NTIS abstract.
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.

Available in PDF, EPUB and Kindle. Book excerpt: For advanced undergraduate and beginning graduate students in atmospheric, oceanic, and climate science, Atmosphere, Ocean and Climate Dynamics is an introductory textbook on the circulations of the atmosphere and ocean and their interaction, with an emphasis on global scales. It will give students a good grasp of what the atmosphere and oceans look like on the large-scale and why they look that way. The role of the oceans in climate and paleoclimate is also discussed. The combination of observations, theory and accompanying illustrative laboratory experiments sets this text apart by making it accessible to students with no prior training in meteorology or oceanography. * Written at a mathematical level that is appealing for undergraduates and beginning graduate students * Provides a useful educational tool through a combination of observations and laboratory demonstrations which can be viewed over the web * Contains instructions on how to reproduce the simple but informative laboratory experiments * Includes copious problems (with sample answers) to help students learn the material.
Download or read book Circulation in the Equatorial Mesosphere in Winter written by B. T. Miers and published by . This book was released on 1969 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Winds observed in the equatorial mesosphere (60-85 km) during December 1968 at Barbados and January 1969 at Colon, Panama are presented. The data were obtained with the high energy Loki system and gun-launched projectiles which expelled radar-reflective, 0.001 inch diameter glass chaff near an apogee of 85 km. Mean meridional profiles were generally less than 15 m/sec with an extreme value of 50 m/sec. In the mean, westerly components dominated the profiles at both stations, with a maximum of approximately 60 m/sec near 70 km over Panama and 40 m/sec in the 65 km region over Barbados. Zonal wind speeds near 70 km over Panama were about 60 m/sec greater than indicated by previous studies. Mesospheric wind profiles in tropical regions were shown to be influenced by synoptic weather patterns and the diurnal tides. There was evidence that the winter hemispheric westerlies extend into the summer hemisphere at 60 km altitude. (Author).
Download or read book The Dynamic Meteorology of the Stratosphere and Mesosphere written by James Holton and published by Springer. This book was released on 2016-06-28 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Wind data from the upper mesosphere over Fort Greely, Alaska, and Thule Air Base, Greenland, are presented. The data were gathered with small meteorological rockets and radar reflective chaff in July 1967. These data show increasing easterly winds with height throughout the mesosphere at high latitudes in summer with maximum speeds up to 92 mps and mean speeds near 50 mps in the 75-80 kilometer region. Diurnal and semidiurnal oscillations are resolved and compared with current theoretical values for atmospheric thermal tides. (Author).
