what is relative humidity, how can it can be increased
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.

Relative humidity is a measure of the amount of moisture in the air relative to the total amount of moisture the air can hold. For instance, if the relative humidity was 50%, then the air is only half saturated with moisture. Warmer air can hold more moisture than colder air. Why is relative humidity important?
