Clouds are a magic show of the sky. Water substance is continually appearing and disappearing. Where does a cloud come from and where does it go? As a cloud physicist I know the sequence of physical causes that brings a cloud into existence and causes it to dissipate. There are only a few cloud physicists among the general populace. But all of us, lay and professionals, can look upon the process with awe and wonder. I do.  2, fiche 3, Anglais, - cloud%20physicist

Kelvin-Helmholtz wave clouds are formed when there are two parallel layers of air that are usually moving at different speeds and in opposite directions. The upper layer of air usually moves faster than the lower layer because there is less friction. In order for us to see this shear layer, there must be enough water vapor in the air for a cloud to form. Even if clouds are not present to reveal the shear layer, pilots need to be aware of invisible atmospheric phenomenon. ... The Kelvin-Helmholtz wave cloud does not last very long because the upper layer of air is usually drier than the lower layer, which results in evaporation of the cloud.  3, fiche 4, Anglais, - Kelvin%2DHelmholtz%20wave%20cloud

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 5, Anglais, - chinook%20arch

Chinook arch: ... It forms in the rising portion of standing waves on the lee side of the mountains.

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.

The planets of our Solar System formed due to two properties of interstellar clouds : rotation and turbulence. When clouds fragment during contraction, individual fragments turn this way and that, each having inherited the angular momentum(spin) of one or a few discrete whorls or eddies in the original clouds. Each cloud fragment(a potential star) would have rotated faster and faster as it contracted, owing to the physical necessity of conserving its angular momentum-much as a skater spins up when he/she folds in her/his arms. Fragments with low angular momentum form the core and fragments with high angular momentum populate a flattened disk orbiting the core, with a shape similar to many galaxies. Often the core itself is fragmented, leading to binary and multiple star systems.  1, fiche 9, Anglais, - cloud%20fragment

Record number: 10, Textual support number: 1 CONT

Billow clouds are created when different layers of wind flow at different velocities resulting in unstable turbulence between the layers. The common name for this instability is Kelvin-Helmholtz instability. Billow clouds are created in the upward branch of each of the "eddies" if the air within this branch has a high enough relative humidity that, upon lifting, the air parcel reaches saturation. Individual billow clouds generally last a few minutes. Billow clouds provide a visible signal to pilots of potentially dangerous turbulence.  3, fiche 10, Anglais, - billow%20cloud
