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.
The condensation of water vapor is a significant weather event, giving us clouds, fog, and precipitation. We have learned above that net-condensation occurs when humidity reaches the saturation point, and that saturation depends as much on air temperature as on the actual quantity of water vapor mixed in with the air.
