con•den•sa•tion n.

''The change of a vapour or gas into liquid form. This change of state is accompanied by the release of latent heat, which alters the adiabatic temperature change in rising air. Condensation in meteorology can be caused by: the cooling of a constant volume of air to dew point, the expansion of a parcel of air without heat input, the evaporation of extra moisture into the air, the fall in the moisture-holding capacity of the air due to changes in both volume and temperature, and contact with a colder material or air mass.''
