  4. What Is Humidity? | NOAA SciJinks – All About Weather

  5. Humidity is the amount of water vapor in the air. If there is a lot of water vapor in the air, the humidity will be high. The higher the humidity, the wetter it feels outside. On the weather reports, humidity is usually explained as relative humidity.

    Humidity is a natural part of our atmosphere, it comes from the amount of water vapor in the air. Water vapor enters the atmosphere by evaporating from the large bodies of water on the Earth’s surface including lakes, oceans, and seas. 97% 1 of the Earth’s water can be found in our oceans 2.

    A 100% relative humidity level would mean that the air is completely saturated with water vapor. Unable to hold any more, it would rain. Colder climates often have lower humidity levels than warmer climates as colder air holds less moisture than warm air. In winter, humidity levels tend to be typically lower.
    Humidity is the concentration of water vapor present in the air. Water vapor, the gaseous state of water, is generally invisible to the human eye. Humidity indicates the likelihood for precipitation, dew, or fog to be present. Humidity depends on the temperature and pressure of the system of interest.

    That difference is expressed as a percentage. For example, a relative humidity of 70 percent means the air is at 70 percent of its water-holding capacity for the present temperature. Cold air cannot hold as much water vapor as warm air can. Thus, as temperature falls, with no change in the amount of water in the air, the relative humidity rises.
    Humidity depends on water vaporization and condensation, which, in turn, mainly depends on temperature. Therefore, when applying more pressure to a gas saturated with water, all components will initially decrease in volume approximately according to the ideal gas law.
