Unformatted text preview: absolute humidity - direct measure of water vapor content of air (g of WV/m^3 air) as air volume changes, absolute humidity changes specific humidity - mass of water vapor in given mass of air (g WV/kg air) as air volume changes, specific humidity does not change relative humidity - amount of water vapor in the air in comparison with the total amount that could be there if air were saturated ratio expressed as a percentage relative humdidty = (actual water vapor in air / capacity) x 100 changes - if water vapor content or water vapor capacity changes, inverse relationship with temperature how dry the atmosphere is Dew point - critical air temperature at which saturation is reached...
