Cork Insulation. Cork is the outer bark of an oak tree that flourishes only in the area surrounding the western Mediterranean Sea. Instead of being fibrous in structure, the bark of the cork oak is composed of tiny cells, so small that there are 200 million of them to every cubic inch of cork bark. These tiny cells give cork a high resistance to the passage of heat. Each cell is filled with still air, and next to a vacuum, still air is the best insulation known. Because the cells are so tiny, no convection currents in the air can be established to reduce its insulation properties. The cellular structure gives the material its high degree of natural moisture resistance. Each tiny cork cell is a perfect geometric shape, having 14 sides. The volume of cork includes more than 75% air. Its thermal conductivity is 0. 26 Btu per square foot per hour per degree temperature difference at 60 degrees F.(metric), and 0. 30 Btu per square foot per degree temperature difference at 180 degrees F(metric).  2, fiche 1, Anglais, - cork%20insulation

COMSAT, or the Communications Satellite Corporation, was created in 1962 with the passage of the Communications Satellite Act. The act authorized the formation of a private corporation to administer satellite communications for the United States. COMSAT was given responsability for many activities including the development of a global satellite communications system, the acquisition and maintenance of ground stations around the world, and the development of new satellite technologies. COMSAT is governed by a Board of Directors elected by the company's shareholders and the president of the United States. Half of the company's shares are owned by major companies such as AT and T, ITT, and Western Union, and the rest are held by members of the public. COMSAT has offices worldwide and its headquarters are located in Washington, D. C.  1, fiche 2, Anglais, - Communications%20Satellite%20Corporation

There are at least three distinct types of cold pool : 1. Large(in areal extent), slow-moving vortices at latitudes poleward of roughly 50deg N & S. They are often over, or immediately downwind of the source regions of polar or arctic air masses, in such areas as the Canadian Arctic or Siberian Russia.... 2. Once cold air from the source region as detailed in(1.) above is caught up in the circulation of mid-latitude depressions, the characteristics of the air mass are altered. Warming from below(over relatively warmer sea surfaces for example), leads to instability developing, and with an accompanying injection of moisture(after a reasonable length of passage over the sea), cloudy convection(showers, thunderstorms) is triggered. Cold pools in these situations are often maxima of such activity, with surface charts showing west or northwesterly airflow, often with cyclonically curved isobars. The cold pool will move in the general synoptic flow, and will eventually warm out(disappear) due to sensible & latent heat exchanges within the environment of the cold pool. However,... sometimes the cold pool will transform into a slow-moving, longer-lasting entity, particularly if the feed of ex-polar air on its western flank is maintained-this occurs in highly meridional situations. 3. A pool of cold air can also become ’detached’ at lower latitudes...  2, fiche 3, Anglais, - cold%20air%20pool

En 1992, deux auteurs anglais, Price et Vaughan, publièrent une étude statistique des gouttes froides, en séparant 3 types : les gouttes froides de type arctique, de type polaire et de type subtropicale, en fonction du courant-jet au voisinage duquel eut lieu le détachement stratosphérique. Ces auteurs montrèrent que les gouttes froides de type subtropical sont plus petite, et durent moins longtemps, que les gouttes froides qui se forment aux latitudes moyennes et polaires.  2, fiche 3, Français, - goutte%20froide
