Mike Moss: Relative humidity is not related to temperature and dew point in quite that direct a manner, although they certainly are interdependent quantities. There are some online calculators ...

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

On a calm, clear night, the ground cools very efficiently by radiating heat back into the atmosphere. This lowers the ...

However, the relative humidity in this case would only be 52%, giving no indication of the true feel of the air. Dew point and frost or snow The dew point is also a useful measure in other seasons.

So, what is the difference, if there really is one? To find out, let’s dive into what dewpoint is and what relative humidity is. Dewpoint is a more direct measure of moisture in the air.

The relative humidity depends on the air temperature, even when the dew point stays constant. In the example above, we have a dew point temperature that stays constant at 65 degrees.

Most people understand relative humidity, but the dew point is a much better measure of how humid it really feels.

There are several ways to measure humidity. The most commonly used is relative humidity, which compares the amount of water vapor in the air to the total amount that air can hold. This measure ...

So, dew point is a proxy measure of the actual amount of water in the air (by weight or pressure), while relative humidity is a measure of the fractional amount of vapor.

Some weather stations measure relative humidity and other key metrics from outside your home.

Comparison As noted earlier, when looking at relative humidity, Alaska is the most humid state. This is a function of the low temperatures. A cold airmass simply cannot hold a lot of moisture.

Working with approximately $2 billion in healthcare construction and renovation projects each year, we can attest to the prevalence of humidity issues among a range of healthcare facilities including ...
