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 1, English, - convectively%20unstable%20air

Les cumulus peuvent [...] grossir suffisamment pour qu'il y ait des averses de pluie, ou même évoluer en cumulonimbus avec orage. On peut rencontrer cette situation : soit dans de l'air chaud convectivement instable sur une grande épaisseur, soit à l'arrière d'un front froid, lorsque à cause d'un flux cyclonique il n'y a pas la moindre subsidence en altitude. 1, record 1, French, - air%20convectivement%20instable
