Humidity is measured using a hygrometer. 1.2 Why is humidity important? Humidity affects many properties of air, and of materials in contact with air. Water vapour is key agent in both weather and climate, and it is an important atmospheric greenhouse gas.
What does 100 percent humidity mean?
Must it be raining when the humidity reaches 100%?
It just means that the air is holding as much moisture as it can at a given temperature, in the form of water vapor, which is an invisible gas. ... Also, the relative humidity at the ground does not have to be 100% to get rainfall.
How is humidity measured percent?
Just like water vapor, relative humidity can be expressed in terms of pressure or density. In both cases it is expressed as a percentage and is calculated by dividing actual vapor pressure by saturation vapor pressure (or actual vapor density by saturation vapor density), then multiplying that number by 100.
