humidity

Definition of humidity in English English dictionary: dampness, especially that of the air; the amount of water vapour in the air; {n} moistness, dampness; You say there is humidity when the air feels very heavy and damp. The heat and humidity were insufferable; water vapor in the atmosphere Absolute humidity is the amount of water vapor in a given quantity of air; it is not a function of temperature Relative humidity is a ratio of actual atmospheric moisture to the maximum amount of moisture that could be carried at a given temperature, assuming constant atmospheric pressure The higher the temperature--other factors remaining constant--the lower the relative humidity (i e the drier the air); The amount of water vapor in the air It is often confused with relative humidity or dew point; The degree of moisture in the air; A general term referring to water vapor in the air; wetness in the atmosphere; Humidity is the amount of water in the air. The humidity is relatively low. Amount of water vapour in the air. One of the most variable characteristics of the atmosphere, humidity is an important factor in climate and weather: it regulates air temperature by absorbing thermal radiation both from the Sun and the Earth; it is directly proportional to the latent energy available for the generation of storms; and it is the ultimate source of all forms of condensation and precipitation. Humidity varies because the water-holding capacity of air is determined by temperature. When a volume of air at a given temperature holds the maximum amount of water vapour possible, the air is said to be saturated. Relative humidity is the water-vapour content of the air relative to its content at saturation. Saturated air has a relative humidity of 100%; near the Earth the relative humidity rarely falls below 30%; The amount of water vapor in the air; The percent concentration of water vapor in the atmosphere; is the quantity of water vapor in the air Relative humidity is the ration between the actual quantity of watervapor and the amount of watervapor that the air can hold at a given temperature; {i} dampness, moistness, mugginess; The ratio of the actual water content of the air to the amount of water the air is capable of holding at a particular temperature; is the amount of water vapor in the air The higher the temperature, the greater the number of water molecules the air can hold "Relative humidity" describes the amount of water in the air compared with how much the air can hold at the current temperature For example, 50% relative humidity means the air holds half the water vapor it is capable of holding; The amount of water vapor content in the air; 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; Generally, a measure of the water vapor content of the air Popularly, it is used synonymously with relative humidity; (Relative)Ratio between the amount of moisture in the air and the greatest amount of moisture the air could hold at the same temperature; The moisture in the air See also: Relative humidity; The amount of water vapor in the air It is often confused with relative humidity or dew point Types of humidity include absolute humidity, relative humidity,and specific humidity; The moisture content of air Relative humidity is the ratio of the amount of water vapor actually present in the air to the greatest amount possible at the same temperature; The moisture in the air See also relative humidity; Is a measure of the amount of water vapour content of the air For related information please see Relative Humidity and Humidex; A general term used to describe the amount of water vapor found in the atmosphere; Generally, some measure of the water vapor content of air; The amount of water vapor in the atmosphere (See relative humidity); The moisture content of the atmosphere at a given time; a measure of the amount of moisture (water vapor) in the air; The condition of the atmosphere in respect of its water vapour content The word 'humidity' used alone generally signifies relative humidity, but various other measures are employed such as humidity mixing ratio, vapour concentration, vapour pressure, specific humidity, dew point etc; Water in air, as a gas Often measured as a percentage, compared to the maximum amount of water vapor the air can contain at that temperature; humidness
absolute humidity: the mass of water vapour in a given volume of air
absolute humidity: Meteorology: In a system of moist air, the ratio of the mass of water vapor present to the volume occupied by the mixture, that is, the density of the water vapor component. Absolute humidity is usually expressed in grams of water vapor per cubic meter or, in engineering practice, in grains per cubic foot. Because this measure of atmospheric humidity is not conservative with respect to adiabatic expansion or compression, it is not commonly used by meteorologists. (Also called ''vapor concentration and vapor density). See relative humidity
