Document Summary
* this is also the most common & easiest way for the air to become saturated and thus for condensation to occur, by changing the air t . ** water vapor content in the air and thus rh varies from day to day, month to month, seasonally and spatial (from place to place). * remember, the colder the air, the less water vapor it can hold. While the warmer the air, the more water vapor it can hold. In meteorology the term adiabatic refers to a parcel of air changing temperature without heat energy being added. ** a parcel of air that contains warm air is less dense (lighter) and thus may rise. As this parcel of air rises in the atmosphere, it will encounter lower pressure and thus expand. As it expands the molecules in it will start to slow down and thus kinetic energy levels will decrease. As this occurs, the t will also decrease.
