the air not only because the presence of water vapor is an
indicator of the potential for precipitation, but the energy
released as water vapor changes states provides the energy for
storms.
Moisture, or humidity, is a general term we will use to

of ways to express the amount of humidity in the air -- the most
common being absolute humidity, relative humidity and mixing
ratio. We will take up each of these shortly.
