humidity (hy -mĭd'ĭ-tē) Pronunciation Key
The amount of water vapor in the atmosphere, usually expressed as either absolute humidity or relative humidity. |
| relative humidity
The ratio of the actual amount of water vapor present in a volume of air at a given temperature to the maximum amount that the air could hold at that temperature, expressed as a percentage. Warm air can hold more water vapor than cool air, so a particular amount of water vapor will yield a lower relative humidity in warm air than it does in cool air. Compare absolute humidity. |
