Absolute Humidity and Relative Humidity. The National Weather Service defines absolute humidity as the actual amount of water vapor in the air, regardless of the air temperature.

Much of the United States deals with humidity on a regular basis especially during the spring and summer. Merriam-Webster dictionary defines humidity as, "a moderate degree of wetness especially ...

We investigate what relative humidity is, why it matters, and what it means for your home.

Another example would be in the winter. If the air temperature were 45 degrees and the dewpoint were 40 degrees, you're dealing with 85% relative humidity. That sounds really steamy!

Now, there's some limitations of using relative humidity. For example, during a snowstorm, the air may be 100% saturated, leading to a relative humidity reading of 100%.

Relative humidity is a much more variable, much less reliable gauge of comfort because it is, well, relative to temperature. When the air's temperature matches its dew point temperature, relative ...

Humidity is the concentration of water vapor present in the air. There are three types of humidity measurements; absolute, relative, and specific humidity.

For example, if you have a station report that included an air temperature of 85 degrees Fahrenheit and a dewpoint of 65 degrees Fahrenheit and you wanted to compute the relative humidity, you ...

Using relative humidity is deceiving when talking about how humid is outside because it is dependent on air temperature. Dew point is the better option.

The hygrometer is the instrument that measures relative humidity, the humidity is relative to the air temperature.

A new study has found a significant correlation between "absolute" humidity and influenza virus survival and transmission. When absolute humidity is low -- as in peak flu months of January and ...

For example, the relative humidity on a given day may vary between 90% in the morning and 38% in the afternoon and it still feels relatively comfortable.
