When an unstable air parcel rises, it cools adiabatically, i.e., without gaining or losing heat. Once its temperature reaches the dew point, the water vapor it contains condenses to form clouds, releasing latent heat. This latent heat provides energy for the parcel to continue rising. However, if the parcel encounters a layer of stable air, where the temperature remains constant or increases with height, it will stop rising. The stable layer acts like a lid on the unstable layer, preventing further ascent. This mechanism is called a temperature inversion, and it often occurs near the top of the planetary boundary layer or in the presence of an upper-level high-pressure system. Entrainment is the process by which surrounding air mixes with the rising parcel, potentially weakening or enhancing its buoyancy. Friction affects the speed and direction of the winds, but it does not directly influence the buoyancy of air parcels. The lifting condensation level is the altitude at which a parcel first becomes saturated, but it is not a mechanism for stopping the rise of unstable air parcels.
