Clouds may also develop as a consequence of human activity. Examples are aircraft condensation trails(contrails), or clouds resulting from industrial processes, such as cumuliform clouds generated by rising thermals above power station cooling towers. Clouds that are clearly observed to have originated specifically as a consequence of human activity will be given the name of the appropriate genus, followed by the special cloud name "homogenitus. "For example, Cumulus cloud formed above industrial plants will be known as Cumulus(and, if appropriate, the species, variety and any supplementary features) followed by the special cloud name homogenitus; for example, Cumulus mediocris homogenitus.  1, fiche 1, Anglais, - homogenitus

Homogenitus : ce nuage est parmi ceux qui sont la conséquence d'activités humaines. L'équipe a cru bon d'ajouter les fameuses traînées de condensation que laissent parfois derrière eux les avions de ligne, car elles ont une influence certaine sur le temps. Quand les traînées paraissent et restent, c'est signe qu'à l’altitude où l'avion vole, l'atmosphère est saturée d'humidité. Alors que lorsqu'elles disparaissent, l'air est plus sec.  1, fiche 1, Français, - homogenitus

Clouds may develop locally in the vicinity of large waterfalls as a consequence of water broken up into spray by the falls. The downdraft caused by the falling water is compensated for by the locally ascending motion of air. These special clouds will be given the name of the appropriate genus, followed by any appropriate species, variety and supplementary feature, and followed by the special cloud name "cataractagenitus"(for example, Cumulus cataractagenitus or Stratus cataractagenitus).  1, fiche 2, Anglais, - cataractagenitus

A foehn cloud formation appearing as a bank of altostratus clouds east of the Rocky Mountains, heralding the approach of a chinook.  2, fiche 4, Anglais, - chinook%20arch

Record number: 4, Textual support number: 1 CONT

When moisture is present, a variety of mountain-wave clouds and lee-wave clouds can form, such as the chinook arch of the Canadian Rocky Mountains west of Calgary, Alberta. The chinook brings relief from the cold of winter, but its most important effect is to melt or sublimate snow : a foot of snow may disappear in a few hours.  3, fiche 4, Anglais, - chinook%20arch

Record number: 4, Textual support number: 2 CONT

Chinook arch: ... It forms in the rising portion of standing waves on the lee side of the mountains. An observer underneath or east of the cloud sees an arch of clear air between the cloud’s leading edge and the mountains below. The cloud appears to converge with the mountains to the north and south due to a perspective effect.  2, fiche 4, Anglais, - chinook%20arch

Les chinooks soufflent donc du sud ou du sud-ouest et peuvent atteindre des vitesses supérieures à 150 km/h. La turbulence causée par le vent est semblable à l'action de l'eau qui frappe une roche. Lorsque l'air descend, des ondes se forment. La crête de l'onde produit une bande nuageuse particulière, parallèle aux montagnes, qu'on appelle une arche de chinook.  3, fiche 4, Français, - arche%20de%20chinook

Representation of the physical and dynamical processes associated with clouds.  2, fiche 5, Anglais, - cloud%20model

Record number: 5, Textual support number: 1 CONT

There are several serious difficulties in including clouds in models. First, cloud properties are largely subgrid-scale. Even the most regular layered cloud systems have wide variations on a 100-km scale, and boundary-layer cumulus clouds can be of a scale less than 1 km.... Second, there is a wide variety of cloud types, each of whose radiative properties varies widely from cloud system to cloud system.... The third, and perhaps most serious difficulty, is that processes of cloud formation and cloud radiative properties have not been satisfactorily related observationally to other meteorological processes.... As a consequence of the limitations discussed above, the current approach of modellers is to make up some "cloud model" based on simple physical arguments, include this parameterization in a GCM simulation, and compare the resulting model cloud climatology with one or several observational climatologies.  3, fiche 5, Anglais, - cloud%20model
