dew point-the temperature at which the water vapor in the air becomes saturated and condensation begins.temperature-the degree of hotness or coldness of a body or environment (corresponding to its molecular activity).ew point. The temperature at which air becomes saturated with water vapor and dew forms. The dew point varies depending on how much water vapor is in the air.
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.
