Wall clouds are formed by a process known as [[Entrainment (meteorology)|entrainment]], when an [[inflow (meteorology)|inflow]] of warm, moist air rises and [[Convergence zone|converges]], overpowering wet, [[rain]]-cooled air from the normally downwind [[downdraft]]. As the warm air continues to entrain the cooler air, the air temperature drops, and the [[dew point]] increases (thus the [[dew point depression]] decreases). As this air continues to rise, it becomes more [[Vapor pressure#Meaning in meteorology|saturated]] with moisture, which results in additional [[cloud]] [[condensation]], sometimes in the form of a wall cloud. Wall clouds may form as a descending of the [[cloud base]] or may form as rising [[scud (cloud)|scud]] comes together and connects to the storm's cloud base.
