Available in PDF, EPUB and Kindle. Book excerpt: An atmospheric phenomenon is considered as 'explained' when we have succeeded in deducing it on the basis of accepted principles of physics. (H. Ertel, Methods and problems of dynamical meteorolo gy,p. l) Until recently, noctilucent clouds were regarded merely as a curious atmos pheric phenomenon, the occurrence of which aroused only limited scientific attention. However, in the last two decades the interest they have been given has markedly increased. The clouds, usually pale blue in colour, may be seen on a clear night at high latitudes. Typical examples are illustrated in the book. Clouds looking like these in daytime would be classified as cirrostratus. What sets noctilucent clouds apart is their occurrence in the middle of the night, their very obvious pale blue colour, and their disappearance into the dawn close to the onset of civil twilight when the Sun is 6° below the horizon. as being set apart from ordinary Noctilucent clouds were first recognized clouds in 1884/1885 and in a series of sightings that followed their return in the summer of 1885. That year marked the beginning of observations and the interpretation of twilight phenomena. The impetus came from the extraordi nary Krakatoa eruption, which was not only one of the most spectacular volcanic eruptions in recorded history, but which also turned out to be a startling event in atmospheric science with repercussions even in our time.

Download or read book Waves in Dusty Space Plasmas written by Frank Verheest and published by Springer Science & Business Media. This book was released on 2001-11-30 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this volume a thorough review is given of waves in dusty plasmas, a fascinating new domain combining plasmas and charged dust, two omnipresent ingredients of the Universe. Spokes and braids observed in the rings of Saturn cannot be explained by gravitation alone, but need the presence of charged dust. Other examples abound, as in zodiacal light, noctilucent clouds, comets and molecular clouds. After discussing charging mechanisms, supported by exciting new experiments, and space observations, the book describes extensions of known plasma modes covering the low frequencies typical for charged dust. Mixing detailed theoretical steps with summaries of expert contributions, a systematic multi-species treatment puts the literature in perspective, suitable also for newcomers. Typical complications like fluctuating dust charges, self-gravitational effects, and size distributions are dealt with, before ending with an outlook to future work and open questions. In this way, experts as well as interested newcomers will find a reliable guide, not just a compendium.

Book excerpt: "Most naturally occurring optical displays can be seen from an airplane, and some are best viewed while airborne. This book is an introduction to optical phenomena in the natural world - primarily in the atmosphere (or "in the air"). It follows a simple approach that can be understood and enjoyed by readers without scientific training. A variety of optical phenomena are illustrated with photographs and explained with simplified line diagrams and descriptions. These phenomena range from everyday sky and sunset colors to the elusive noctilucent clouds and aurora, as well as a whole world of too-often-ignored occurences such as sun glitter patterns on bodies of water, colorful ringed glories and coronas, rainbows that cling to the clouds below a high-flying airplane, and ice halos that spring up as an airplane passes through high-altitude ice clouds"--

Download or read book 101 Objects to See in the Night Sky written by Robin Scagell and published by . This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The perfect starter astronomy guide to night viewing. 101 Objects to See in the Night Sky is a fun and practical guide to identifying and observing 101 of the most fascinating and exciting sights in the northern night sky. Designed for newcomers to astronomy, the book explains what can be seen using the naked eye, binoculars or a telescope. In the book, professional astronomer Robin Scagell shows the novice astronomer where to look in the sky to see a particular object, or group of objects or sights. They may be a planet, its rings or satellites, a series of lunar craters, a constellation, asteroids, meteors, a nebula, galaxy or star cluster, for example. He describes the object in detail and gives observing tips to improve viewing skills. Informative "Where to find it" instructions and "What you'll see" explanations for each object give night sky viewers an extra hand. A concise "fact file" is provided for each object, and readers can award themselves "points" for their skill in finding the object, with higher scores given for spotting the night sky's more elusive or hard-to-see features. The book is organized by season -- winter, spring, summer, fall -- with an opening section on "things you need to know," such as marker objects (for example, Sirius, the brightest star in winter's night sky) and how to use them to search beyond. It also covers such topics as asteroids and dwarf planets, noctilucent clouds, northern lights, the International Space Station, sunspots, eclipses and much more. 101 Objects to See in the Night Sky is an ideal guide for astronomy novices and classrooms.

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 Stamping the Earth from Space written by Renato Dicati and published by Springer. This book was released on 2017-01-10 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: This unique book presents a historical and philatelic survey of Earth exploration from space. It covers all areas of research in which artificial satellites have contributed in designing a new image of our planet and its environment: the atmosphere and ionosphere, the magnetic field, radiation belts and the magnetosphere, weather, remote sensing, mapping of the surface, observation of the oceans and marine environments, geodesy, and the study of life and ecological systems. Stamping the Earth from Space presents the results obtained with the thousands of satellites launched by the two former superpowers, the Soviet Union and the United States, and also those of the many missions carried out by the ESA, individual European countries, Japan, China, India, and the many emerging space nations. Beautifully illustrated, it contains almost 1100 color reproductions of philatelic items. In addition to topical stamps and thematic postal documents, the book provides an extensive review of astrophilatelic items. The most important space missions are documented through event covers and cards canceled at launch sites, tracking stations, research laboratories, and mission control facilities.
