Most brief but violent disturbances in Earth's wind systems involve large areas of ascending and descending air.... a thunderstorm is said to develop when the atmosphere becomes "unstable to vertical motion[.

Hurricane spiral bands consist of individual convective cells associated with small-scale cumulus convection. The thunderstorms within the spiral bands are organized into regions of rising and sinking air. In contrast to the motion of the band, which moves considerably slower than the mean wind speed, the individual cells tend to move with the mean wind in the layer in which they are embedded. These convective cells, which have typical lifetimes of 20-40 min, are a result of a general lifting within the band of convectively unstable air.  1, record 13, English, - convectively%20unstable%20air

Smoke plumes that rise through the environment due to buoyancy or momentum become diluted with environmental air, where the rate of dilution is proportional to the rise rate of the plume. The entrainment coefficient is this constant of proportionality. This concept of lateral entrainment does not work well for convective thermals in the atmospheric boundary layer. One reason is that boundary layer thermals are part of a large overturning circulation involving the whole boundary layer during statically unstable conditions of free convection, rather than being thin currents of rising smokestack air.  2, record 18, English, - entrainment%20coefficient

Cloud formation makes the convection process visible. An unstable atmospheric column will lead to updrafts. If the air below is moist, the updraft will lead to condensation into droplets. The condensation process accelerates the updraft owing to the release of latent heat. Examples are the various types of cumulus clouds(e. g., cumulus, cumulus congestus, cumulonimbus).  2, record 20, English, - condensation%20process

Record number: 21, 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, record 21, English, - billow%20cloud

Backward curved and backward inclined blade fans. Backward curved and backward inclined blades are slightly less efficient, cost less, and generate slightly more noise than the airfoil type. The number of blades is usually ten to sixteen and the fan scroll is the same as for airfoil fans. Backward curved blades... are constant thickness airfoil blades and are preferred over straight backward inclined blades... because they allow smoother air flow and are stronger. Backward curved blade fans will operate over the full range of air flow from wide open to shut off, whereas backward inclined blade fans are unstable under flow condition below the design point. These fans are used in industrial applications in which fouling of the blades by airborne contaminants would minimize the efficiency advantage of airfoil blade fans.  2, record 22, English, - backward%20inclined%20fan

Ventilateurs à pales courbées et inclinées vers l'arrière. Les pales courbées et inclinées vers l'arrière sont un peu moins efficaces, coûtent moins cher et sont légèrement plus bruyantes que les pales à profil aérodynamique. Il y a habituellement dix à seize pales montées sur la roue et le carter spiralé est identique à celui d'un ventilateur à pales à profil aérodynamique. Les pales courbées vers l'arrière [...] constituent des pales à profil aérodynamique d'épaisseur constante et sont plus utilisées que les pales droites inclinées vers l'arrière [...] parce qu'elles génèrent un débit plus uniforme et sont plus durables. Les ventilateurs à pales courbées vers l'arrière fonctionnent sur toute la gamme de débits d'air, de la position complètement ouverte à la position complètement fermée, tandis que le fonctionnement des ventilateurs à pales inclinées vers l'arrière devient instable lorsque le débit est inférieur à la valeur du point de calcul. Lorsque ces ventilateurs à pales à profil aérodynamique sont utilisés dans l'industrie, l'encrassement des pales entraîné par des particules contaminées en suspension dans l'air réduit le rendement de ce type de ventilateurs.  2, record 22, French, - ventilateur%20%C3%A0%20r%C3%A9action
