Atmospheric Moisture :- Humidity
temperature, there is a definite limit to the maximum quantity of
mosisture that can be held by the air. This limit is known as the
saturation point. Humidity can be measured by a hygrometer or
psychrometer.
Relative Humidity is the ratio between the amount of water vapour
actually present in an air mass can hold at that temperature. It is
expressed as a percentage. At the saturation point, relative humidity
is 100 percent.
Absolute Humidity is the actual amount of moisture present in air. The
amount of water vapour per unit volume of air is usually expressed in
grams per cubic meter. It is a measure of the quantity of water that
can be extracted from the atmosphere as precipitation.
Specific Humidity is the ratio of the weight of water vapour to the
weight of moist air . Exressed in units of grams of water vapour per
kilogram of moist air, specific humidity is often used to describe the
moisture characteristic of a large mass of air.
