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.

Entre deux masse d'air dont les propriétés sont différentes, il existe une zone de transition, appelée zone frontale, dont l'épaisseur varie de quelques décamètres à quelques hectomètres, et dans laquelle les éléments météorologiques passent rapidement de leur valeur dans l'une des masses d'air à leur valeur dans l'autre. À l'échelle des cartes météorologiques, on peut assimiler cette zone à une surface, à laquelle on donne le nom de surface de discontinuité. Ces surfaces sont plus ou moins inclinées par rapport à la verticale, elles coupent donc le sol suivant des lignes auxquelles on donne le nom de fronts.
