https://simple.wikipedia.org/wiki/HumidityHumidity means water vapor in the air, but not to liquid droplets in fog, clouds, or rain. Deserts usually have low humidity, and tropical regions have high humidity. The word "humid" often means that the humidity is high, which gives the feeling of being very damp (wet air), stuffy, or even sweltering when the temperature is also high. When the humidity is low, the air can be …

https://simple.wikipedia.org/wiki/Relative_humidityRelative humidity is a way of describing how much humidity is present in the air, compared to how much there could be. Meteorologists often use the relative humidity as a measurement to describe the weather at various places.. When the temperature is warm, more water vapor can be in the air than when it is cold. If the actual amount of vapor is compared to the total amount …
