Summary

Description
Français : L’entraînement atmosphérique est un phénomène météorologique qui se produit entre un écoulement turbulent et un autre laminaire. En général, ce terme est utilisé pour désigner la capture d'air sec dans un courant ascendant humide, en particulier dans un orage ou un cyclone tropical. Il s'agit donc du mélange de l'air de l'environnement dans le courant ou dans le nuage qu'il crée. Le détraînement est l'effet inverse. Il s'agit donc du flux sortant d'un élément convectif, transférant une partie de sa chaleur et de son humidité à l'atmosphère environnante. Ce phénomène se produit surtout au sommet des nuages convectifs, mais également dans la boucle de retour des zones d'entraînement, ce qui permet de modifier graduellement l'environnement à ce niveau.
English: Air training is a meteorological phenomenon that occurs between turbulent flow and another laminar. In general, this term is used to refer to the capture of dry air in an humid updraft, especially in a storm or a hurricane. It is therefore the mixing of environmental air in the current or in the cloud that it creates. The detrainment is the opposite effect. Therefore the outflow of a convective element, transferring some of its heat and moisture to the surrounding atmosphere. This phenomenon occurs especially at the top of convective clouds, but also in the training areas return loop, which allows to gradually change the environment at this level.
