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.
Condensation can actually occur while the temperature is rising, as it does all the time in a cloud. That is, when condensation starts, the temperature rises as a result of the condensation. Condensation occurs when more water vapour is added to the atmosphere than can be kept apart by the atmosphere at its present temperature. Once water vapour is colliding, the air must be able to knock the water vapour molecules apart or, heat is released and we have condensation. Loss of heat comes from the water vapour sticking together, and it takes heat from the air to keep it from sticking. So, when we have a lot of water vapour. air must have that heat or the water sticks together.
