Mathematically, absolute humidity is defined as the mass of the water vapour divided by the volume of the air and water mixture, which is expressed as, Where mH2o = Mass of the water vapour [2] Humidity indicates the likelihood for precipitation, dew, or fog to be present. If the relative humidity is 100 percent, which means the dew point temperature and absolute air temperature are both the same, precipitation is unlikely. Water vapour would have to come out of the atmosphere in the liquid form if the air were to be cooled still further, which would typically happen as fog or precipitation.
