Cloud formation 夠竟係吸定放latent heat?

Formation of cloud requires a continuation of the lifting process. It is assisted by the property of water of giving off heat when changing from vapor to liquid and solid states, the latent heats of condensation and of deposition, respectively. (If the vapor first changes to a liquid before freezing, then we also have the latent heat of condensation released and followed by the release of the latent heat of freezing.) This additional heat release warms the air parcel. In doing so, the buoyancy of the parcel relative to the surrounding air increases, and this contributes to the parcel’s further rise. We can see the continued ascent of these parcels in cumulus clouds that reach great vertical growth.

So the answer is : formation of cloud is actually a process that the latent heat released to the environment.
