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.

Humidity is simply the amount of water vapor in the air. The warmer the air, the more water vapor it can hold, which is why tropical areas tend to feel very humid. Relative humidity is the amount of water vapor the air can hold RELATIVE to how much water vapor that air can hold. It is temperature dependent. As air warms and cools, its relative humidity will fall and rise even though the amount of water vapor does not change.
