Best Answer: With all other things remaining the same, relative humidity will increase as temperatures decrease. Since relative humidity is a ratio (in percent) of the actual amount of water vapor in the atmosphere compared to the saturation amount, if the saturation amount decreases, the ratio must increase.

First, you should understand that the temperature of the air influences the amount of water vapor that can be bound to the molecules of air. Water vapor capacity increases with temperature increase. There are three parcels of air, each in separate containers. Only relative values of moisture and temperature are shown. At low temperatures, the air will hold only two parts of water vapor. As the temperature increases, it will hold 6, then 12 parts of water vapor.
