As moist air is lifted and cooled, water vapor eventually condenses, which then allows for huge amounts of latent heat energy to be released, feeding the storm. 1  Condensation is a warming process. 2  Latent heat of fusion describes both changing from solid to liquid and from liquid to solid.
While condensation does cool the air inside of the air parcel, in order for that cooling to occur, that parcel must release heat into the surrounding environment. Thus, when speaking about the effect of condensation on the overall atmosphere, it warms it. Here's how it works: Remember from chemistry class that molecules in a gas are energetic and move very fast, while those in a liquid move slower. In order for condensation to happen, the water vapor molecules must release energy so that they can slow their movement. (This energy is hidden and is therefore called latent heat .). A number of well-known weather phenomenon are caused by condensation, including: 1  Dew. 2  Fog.
