Humidity \Hu*mid"i*ty\, n. [Cf. F. humidit['e].]

  1. Moisture; dampness; a moderate degree of wetness, which is perceptible to the eye or touch; -- used especially of the atmosphere, or of anything which has absorbed moisture from the atmosphere, as clothing.

  2. Specifically: The content of water vapor in the air, expressed as a percent of the maximum amount of water vapor that the air can hold at the given temperature; also called relative humidity. The capacity of the air to hold moisture increases with temperature, so if the temperature changes without changing the absolute content of the atmospheric moisture, the relative humidity will also change.

    relative humidity Same as humidity[2].

    Note: In hygrometrical reports (as of the United States Signal Service) complete saturation of the air by water vapor is designated by a relative humidity of 100, and its partial saturation by smaller numbers in direct proportion to the actual content of water vapor.

Douglas Harper's Etymology Dictionary

late 14c., from Old French humidité, from Latin humiditatem (nominative humiditas), from humidus (see humid).


n. 1 dampness, especially that of the air. 2 the amount of water vapour in the air.


n. wetness in the atmosphere [syn: humidness]

Humidity (film)

Humidity is a 2016 Serbian drama film directed by Nikola Ljuca. It was selected as one of five films that could be selected as the Serbian submission for the Best Foreign Language Film at the 89th Academy Awards.


Humidity is the amount of water vapor in the air. Water vapor is the gaseous state of water and is invisible. Humidity indicates the likelihood of precipitation, dew, or fog. Higher humidity reduces the effectiveness of sweating in cooling the body by reducing the rate of evaporation of moisture from the skin. This effect is calculated in a heat index table or humidex. The amount of water vapor that is needed to achieve saturation increases as the temperature increases. As temperature decreases, the amount of water vapor needed to reach saturation also decreases. As the temperature of a parcel of air becomes lower it will eventually reach the point of saturation without adding or losing water mass. The differences in the amount of water vapor in a parcel of air can be quite large, for example; A parcel of air that is near saturation may contain 28 grams of water per cubic meter of air at −1 °C, but only 8 grams of water per cubic meter of air at −12 °C

There are three main measurements of humidity: absolute, relative and specific. Absolute humidity is the water content of air at a given temperature expressed in gram per cubic meter. Relative humidity, expressed as a percent, measures the current absolute humidity relative to the maximum (highest point) for that temperature. Specific humidity is a ratio of the water vapor content of the mixture to the total air content on a mass basis.

Humidity (album)

Humidity (2000) is an album by the American ambient musician Robert Rich. It is a three disc set of live material recorded in 1998.

Disc one was recorded on April 2, 1998 at Stanford University’s KZSU radio station as part of their annual Day of Noise event.
