Available in PDF, EPUB and Kindle. Book excerpt: Pour améliorer la connaissance des nuages de cristaux de glace de la haute troposphère, des programmes de recherche internationaux de grande ampleur ont été mis en place ces dernières années. Ce travail s'inscrit dans le cadre de l'expérience ICE (International Cirrus Experiment) et de la campagne en préparation EUCREX (EUropean Cloud and Radiation EXperiment). Le seul moyen permettant une étude globale, à l'échelle planétaire des cirrus est l'observation satellitaire. Ceci a nécessité la mise au point de codes radiatifs adaptés au cas des particules non sphériques. Nous avons étudié des modèles de tels nuages, en faisant en premier lieu l'hypothèse qu'ils sont composés de cristaux de glace de forme cylindrique. Ces résultats ont été utilisés pour interpréter l'observation satellitaire des cirrus semi-transparents. Cette application concerne la télédétection satellitaire à l'aide des canaux infrarouges à 11 μm et 12 μm du radiomètre AVHRR (Advanced Very High Resolution Radiometer) porté sur le satellite NOAA 9 (National Oceanic and Atmospheric Administration). Afin d'effectuer une modélisation plus fine des cirrus, nous avons fait ensuite l'hypothèse qu'ils sont constitués de cristaux, dont la structure de base est hexagonale. Nous avons utilisé tout un ensemble d'observations radiatives (lidar, radiométrie infrarouge et visible) pour caractériser les propriétés optiques moyennes d'un cirrus, des caractéristiques microphysiques ont été déduites et sont tout à fait en accord avec l'interprétation des observations satellitaires. Nous avons étudié le cas où les particules de glace ont une orientation privilégiée dans le cirrus. Le calcul approché du transfert radiatif dans un tel milieu a été mis au point et les effets radiatifs dus à cette anisotropie ont été quantifiés

Available in PDF, EPUB and Kindle. Book excerpt: These proceedings are based upon introductory talks, research reports and discussions from the NATO Advanced Workshop on the "Morphology and Dynamics of the Polar Cusp", held at Lillehammer, Norway, 7-12 May, 1984. The upper atmosphere at high latitudes is called the "Earth's win dow to outer space". Through various electrodynamic coupling process es as well as through direct transfer of particles many geophysical effects displayed there are direct manifestations of phenomena occurring in the deep space. The high latitude ionosphere will also exert a feedback on the regions of the magnetosphere and atmosphere to which it is coupled, acting as a momentum and energy source and sink, and a source of particles. Of particular interest are the sections of the near space known as the Polar Cusp. A vast portion of the earth's magnetic field envelope is electrically connected to these regions. This geometry results in a spatial mapping of the magnetospheric pro cesses and a focusing on to the ionosphere. In the Polar Cusps the solar wind plasma has also direct access to the upper atmosphere. The polar regions are thus of extreme importance when it comes to under standing the physical processes in the near space and their effect on our environment. The Introductory Talks given at this workshop provided a common background for discussing and understanding the physics of the Polar Cusp. By this book we will make the information which thus was provid ed to the participants of the workshop accessible to a wider audience.

Book Synopsis Climate and the British Scene by : Gordon Manley
Download or read book Climate and the British Scene written by Gordon Manley and published by . This book was released on 1962 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: From Chaucer's sweet April showers to the peasoupers of Sherlock Holmes the British scene cannot be contemplated without climate entering in. This edition is exclusive to newnaturalists.com In this book Professor Manley shows us the best and worst of our much-maligned climate. He traces the subtle influence of sunshine and cloud, of dew, mist, rain, hail and snow, of heat and cold on the changing scene through the seasons. We often apologise for our climate, but in many ways it is the best in the world. No great extremes of heat or cold, no dreaded droughts, no destructive hurricanes, yet a marked seasonal rhythm with lots of little surprises. The richness of plant and animal life, the extremely high productivity of our farmlands, the fleeting beauties of our landscape - all are closely linked with Britain's climate. It may justly be claimed that this is the first book to attempt scientifically to trace these intimate yet elusive relationships.
