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.
Best Answer: Water vapor is the dominant greenhouse gas in the atmosphere. Water vapor high in the atmosphere can produce 'noctiluminescent' clouds, primarily from the space shuttle exhaust. At ground level it makes things humid and unpleasant, though it does prevent plant dessication. Dew and fog can be an important source of moisture in some environments. A broad question.
