Wall clouds can range from a fraction of a mile up to nearly five miles in diameter, and normally are found on the south or southwest (inflow) side of the thunderstorm. Even though this cloud is lowering, it remains attached to the rain free cloud base of the thunderstorm. It is usually located south or southwest of the visible precipitation area, and marks the strongest updraft in the thunderstorm. The wall cloud develops as the strong updraft draws in surface moisture from several miles away. 3, record 1, English, - wall%20cloud

"Wall cloud" also is used occasionally in tropical meteorology to describe the inner cloud wall surrounding the eye of a tropical cyclone, but the proper term for this feature is "eyewall. " 3, record 1, English, - wall%20cloud

Le précurseur typique de la tornade est le mur de nuages. C'est une partie de la base du nuage qui semble s'abaisser vers le sol. On le trouve normalement sur le flanc arrière droit de l'orage. Autrement dit, si l'orage arrive de l'ouest, il faut regarder vers sa partie sud-ouest. Le mur de nuages se forme dans la zone sans précipitations et montre généralement un mouvement de rotation, sous la base du nuage. 3, record 1, French, - mur%20de%20nuages

Tropical cyclone [is a] cyclone of tropical origin of small diameter(some hundreds of kilometres) with minimum surface pressure in some cases less than 900 hPa, very violent winds and torrential rain; sometimes accompanied by thunderstorms. It usually contains a central region, known as the "eye" of the storm, with a diameter of the order of some tens of kilometres, and with light winds and more or less lightly clouded sky. 5, record 3, English, - tropical%20cyclone

Tropical cyclones are experienced in several areas of the world. In general, they form over the tropical oceans (except the South Atlantic and the eastern South Pacific) and affect the eastern and equatorward portions of the continents. They occur in the tropical North Atlantic (including the Caribbean Sea and Gulf of Mexico), the North Pacific off the west coast of Mexico and occasionally as far west as Hawaii, the western North Pacific (including the Philippine Islands and the China Sea), the Bay of Bengal and the Arabian Sea, the southern Indian Ocean off the coasts of Madagascar and the northwest coast of Australia, and the South Pacific Ocean from the east coast of Australia to about 140°W. 6, record 3, English, - tropical%20cyclone

By international agreement, tropical cyclones have been classified according to their intensity as follows: 1) tropical depression, with winds up to 17 m s-1(34 knots); 2) tropical storm, with winds of 18-32 m s-1(35-64 knots); and 3) severe tropical cyclone, hurricane or typhoon, with winds of 33 m-1(65 knots) or higher. It should be noted that the wind speeds referred to above are 10-min average wind speeds at standard anemometer level (10 m), except that in the United States, 1-min average wind speeds are used. 6, record 3, English, - tropical%20cyclone

Toujours associés à une profonde dépression, les cyclones tropicaux sont accompagnés de vents violents dépassant généralement 100 kilomètres à l'heure et de pluies diluviennes pouvant dépasser 300 millimètres en 24 heures. La zone couverte par un tel phénomène est quasi circulaire avec un diamètre de quelques centaines de kilomètres à un millier de kilomètres et les masses nuageuses très épaisses qui l'accompagnent atteignent la tropopause, soit à ces latitudes, une quinzaine de kilomètres d'altitude. Les vents violents engendrent dans la zone affectée par le cyclone une mer démontée tandis que se développe, jusqu'à des milliers de kilomètres du centre, une houle caractéristique constituant souvent un signe précurseur de l'approche du phénomène. Autres signes, la chute brutale de la pression, parfois plusieurs dizaines d'hectopascals par heure et l'apparition de nuages caractéristiques. 5, record 3, French, - cyclone%20tropical

"CDO" is an acronym that stands for "central dense overcast. "This is the cirrus cloud shield that results from the thunderstorms in the eyewall of a tropical cyclone and its rainbands. Before the tropical cyclone reaches hurricane strength(33 m/s, 64 kts [knots], 74mph), typically the CDO is uniformly showing the cold cloud tops of the cirrus with no eye apparent. Once the storm reaches the hurricane strength threshold, usually an eye can be seen in either the infrared or visible channels of the satellites. 1, record 4, English, - central%20dense%20overcast

«CDO» est un acronyme pour «central dense overcast», soit en français «couverture nuageuse centrale dense». C'est le bouclier de cirrus qui résulte de la présence de nuages orageux dans le mur de l'œil d'un cyclone. Avant que la dépression n'atteigne le stade de cyclone (64 kt [nœuds] ou 33 m/s), d'une manière générale, la CDO est représentée par une couverture uniforme de nuages froids et denses sans œil apparent. Une fois que le stade cyclone est atteint un œil apparaît en son centre et peut être visible à la fois sur les canaux visibles et infra rouges des images satellite. 1, record 4, French, - couverture%20nuageuse%20centrale%20dense
