PPT-Humidity & Precipitation

Water Vapour in Atmosphere Amount of water vapour in atmosphere humidity is measured by an instrument called hygrometer Significance of Atmospheric Moisture Water vapour absorbs . ABSOLUTE HUMIDITY:. Absolute humidity (expressed as grams of water vapor per cubic meter volume of air) is a measure of the actual amount of water vapor (moisture) in the air, regardless of the air's temperature. The higher the amount (weight) of water vapor per kilogram, the higher the absolute humidity. . Humidity. Amount of water vapor in the air. Water vapor adds pressure (called vapor pressure) to the air. Saturated air is air that is filled with water vapor to capacity. Capacity is temperature dependent – warm air has a much greater capacity. Humidity refers to the amount of moisture (water vapor) in the surrounding air.. Relative.
