The ratio of the actual amount of water vapor (absolute humidity) present in the air to the saturation point at the same temperature, usually expressed as a percentage
The percentage of water in an atmosphere relative to the maximum possible at that temperature and pressure
The ratio of the amount of water vapor actually in the air (absolute humidity) compared to the amount of water vapor the air can hold at that temperature and pressure; expressed as a percentage
the ratio, in percent, of the amount of moisture in a volume of air to the total amount which that volume can hold at the given temperature and atmospheric pressure Relative humidity is a function of the actual moisture content of the air, the temperature, and the atmospheric pressure (Schroeder and Buck 1970)
the ratio of the actual water vapor pressure at a given time to the vapor pressure that would occur if the air were saturated at the same ambient temperature
The ratio, expressed as a percentage, of the amount of water vapor or moisture in the air to the maximum amount of moisture that the air would hold at the same dry-bulb temperature and atmospheric pressure (RH can vary from 0 to 100 %)
the ratio of the partial pressure of water to the saturation vapor pressure, also called saturation ratio; often expressed as a percentage
the ratio of the amount of water in the air at a give temperature to the maximum amount it could hold at that temperature; expressed as a percentage
The ratio of water vapor in the air to the maximum amount of vapor the air can hold at a given temperature and pressure Fire behavior is dependent on, and can be predicted from, relative humidity
The ratio of the amount of water vapor in the air at a specific temperature to the maximum capacity of the air at that temperature
The amount of water vapor in the air, compared to the amount the air could hold if it was totally saturated (Expressed as a percentage)
(%) The ratio of the actual amount of water vapor in the air to the maximum it can hold at a given temperature, multiplied by 100
The ratio of the amount of moisture in the air, to the maximum amount of moisture that air would contain if it were saturated The ratio of the actual vapor pressure to the saturated vapor pressure
The (dimensionless) ratio of the actual vapor pressure of the air to the saturation vapor pressure The corresponding ratios of specific humidity or of mixing ratio give approximations of sufficient accuracy for many purposes in meteorology The relative humidity is usually express in percent Also called humidity See absolute humidity, dew point
Relative humidity is a measure of the amount of moisture in the air It is expressed in a percentage of how much moisture the air could possibly hold The "wetter or damper" the air feels the higher the relative humidity The drier the air feels the lower the relative humidity
the amount of water vapor (vapor pressure) in a given parcel of air divided by the maximum amount of water vapor the parcel of air could contain at a given temperature (saturation vapor pressure) before it would begin to condense into water droplets
the amount of water vapor in the air expressed as the ratio between the measured amount and the maximum possible amount (the saturation point at which water condenses as dew)
A type of humidity that considers the ratio of the actual vapor pressure of the air to the saturation vapor pressure It is usually expressed in percentage
The amount of water vapor in the air compared to the amount of water vapor that the air can hold at a given temperature For example, if the relative humidity is 50 percent, then the amount of water vapor in the air is half of what the air could actually hold at that temperature
The ratio of the amount of water vapor in the atmosphere to the amount necessary for saturation at the same temperature Relative humidity is expressed in terms of percent and measures the percentage of saturation
