  1. humidity, humidnessnoun

    wetness in the atmosphere

GCIDE

  1. Humiditynoun

    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.

Wiktionary

  1. humiditynoun

    dampness, especially that of the air.

  2. humiditynoun

    the amount of water vapour in the air.

Samuel Johnson's Dictionary

  1. Humiditynoun

    That quality which we call moisture, or the power of wetting other bodies. It differs very much from fluidity, depending altogether on the congruity of the component particles of any liquor to the pores or surfaces of such particular bodies as it is capable of adhering to. Thus quicksilver is not a moist liquor, in respect to our hands or clothes, and many other things it will not stick to; but it may be called so in reference to gold, tin, or lead, to whose surfaces it will presently adhere. And even water itself, that wets almost every thing, and is the great standard of humidity, is not capable of wetting every thing; for it stands and runs easily off in globular drops on the leaves of cabbages, and many other plants; and it will not wet the feathers of ducks, swans, and other water-fowl. John Quincy

    Etymology: humidité, Fr. from humid.

    We’ll use this unwholsome humidity, this gross watry pumpion: we’ll teach him to know turtles from jays. William Shakespeare.

    O blessing-breeding sun, draw from the earth
    Rotten humidity: below thy sister’s orb
    Infect the air. William Shakespeare, Timon of Athens.

    Young animals have more tender fibres, and more humidity, than old animals, which have their juices more exalted and relishing. John Arbuthnot, on Diet.

  1. Humidity

    Humidity is the concentration of water vapor present in the air. Water vapor, the gaseous state of water, is generally invisible to the human eye. Humidity indicates the likelihood for precipitation, dew, or fog to be present. Humidity depends on the temperature and pressure of the system of interest. The same amount of water vapor results in higher relative humidity in cool air than warm air. A related parameter is the dew point. The amount of water vapor needed to achieve saturation increases as the temperature increases. As the temperature of a parcel of air decreases it will eventually reach the saturation point without adding or losing water mass. The amount of water vapor contained within a parcel of air can vary significantly. For example, a parcel of air near saturation may contain 28 g of water per cubic metre of air at 30 °C (86 °F), but only 8 g of water per cubic metre of air at 8 °C (46 °F). Three primary measurements of humidity are widely employed: absolute, relative, and specific. Absolute humidity is expressed as either mass of water vapor per volume of moist air (in grams per cubic metre) or as mass of water vapor per mass of dry air (usually in grams per kilogram). Relative humidity, often expressed as a percentage, indicates a present state of absolute humidity relative to a maximum humidity given the same temperature. Specific humidity is the ratio of water vapor mass to total moist air parcel mass. Humidity plays an important role for surface life. For animal life dependent on perspiration (sweating) to regulate internal body temperature, high humidity impairs heat exchange efficiency by reducing the rate of moisture evaporation from skin surfaces. This effect can be calculated using a heat index table, also known as a humidex. The notion of air "holding" water vapor or being "saturated" by it is often mentioned in connection with the concept of relative humidity. This, however, is misleading—the amount of water vapor that enters (or can enter) a given space at a given temperature is almost independent of the amount of air (nitrogen, oxygen, etc.) that is present. Indeed, a vacuum has approximately the same equilibrium capacity to hold water vapor as the same volume filled with air; both are given by the equilibrium vapor pressure of water at the given temperature. There is a very small difference described under "Enhancement factor" below, which can be neglected in many calculations unless great accuracy is required.

  1. humidity

    Humidity is a measure of the amount of water vapor present in the air. It is usually expressed as a percentage, which indicates the presence of water vapor in the air compared to the maximum amount of water vapor the air could hold at the same temperature. It plays a significant role in weather conditions and can affect human comfort and health.

Webster Dictionary

  1. Humiditynoun

    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. Etymology: [Cf. F. humidit.]

  1. Humidity

    Humidity is the amount of water vapor in the air. Water vapor is the gas phase 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, used during summer weather. There are three main measurements of humidity: absolute, relative and specific. Absolute humidity is the water content of air. Relative humidity, expressed as a percent, measures the current absolute humidity relative to the maximum 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.
