So, if condensation is taking place, latent heat is being released to the surrounding air. So you have two opposing trends going on at the same time within this parcel of air. It's rising and cooling, but it's also condensing and being warmed. Which one will win out? That is, will the air get colder, or will it get warmer? Well, what happens is that the air will still cool off, but not as fast. If water vapor in the air is condensing, the adiabatic rate is less. The air is only cooling off at a rate of about 5 degrees C/1000 meters (3.3 deg per 1000 feet). This is called the Saturated adiabatic lapse rate (or the wet adiabatic lapse rate, or the moist adiabatic lapse rate, depending on the textbook you are using). The saturated lapse rate varies with the original temperature of the air parcel, but 5 degrees C/1000 meters is a commonly used value. 6, record 1, English, - saturated%20adiabatic%20lapse%20rate

The pseudoadiabatic lapse rate is so close to the moist adiabatic lapse rate that meteorologists tend to ignore this difference and often refer to them synonymously. In fact, on adiabatic charts (or pseudoadiabatic charts), the moist adiabatic lapse rate lines are referred to interchangeably as moist, saturated, or pseudoadiabatic. 7, record 1, English, - saturated%20adiabatic%20lapse%20rate

Owing to the release of latent heat, this lapse rate is less than the dry-adiabatic lapse rate (...) 3, record 1, English, - saturated%20adiabatic%20lapse%20rate

La masse volumique de l'air peut être facilement calculée grâce à l'approximation du gaz parfait. [...] Un fluide est dit parfait lorsque son mouvement peut être décrit par un modèle mathématique qui ne prend pas en compte le processus de viscosité [...] et de conduction thermique [...] Les seuls efforts de surface à considérer sont les efforts de pression. Les transformations dans un écoulement de fluide parfait sont réversibles, et l'apport de chaleur massique est supposé nul, ce qui implique un mouvement adiabatique. Le mouvement d’un fluide parfait est donc isentropique, dans les domaines fluides exempts de discontinuités. 1, record 2, French, - mouvement%20adiabatique

La condensation de l'eau dans le nuage a toujours pour origine un refroidissement par détente adiabatique associé à un mouvement ascendant de l'air. Dans la basse atmosphère(domaine de la troposphère), ces courants ascendants peuvent avoir plusieurs causes :[...] Le soulèvement d’une masse d’air, soit par une autre masse d’air plus dense le long d’une surface frontale(nuages de détente synoptique), soit par un massif montagneux(nuages orographiques). Les nuages de détente synoptique comme leur nom l'indique, intéressent de vastes secteurs de l'atmosphère et leur extension horizontale peut couvrir plusieurs centaines de milliers de kilomètres carrés, leur épaisseur étant de l'ordre de 2 000 à 4 000 mètres. Les pluies qui leur sont associées ont un caractère continu(durant plusieurs heures), mais sont habituellement d’intensité modérée(quelques millimètres par heure). 2, record 3, French, - nuage%20d%26rsquo%3Bascendance%20synoptique
