There are various ways to measure the amount of water vapor in the atmosphere. The amount of moisture a given parcel of air can hold is dependent on the ambient temperature. Higher temperatures mean ...

NORFOLK, Va. — Most summer days, you hear us talk about “humidity” when describing how the air feels. While many people are familiar with the term relative humidity — the percentage of water vapor in ...

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

Industry leaders realized hundreds of years ago that their processes and machines operate best when the indoor relative humidity is maintained at an optimum level for their process. They found it was ...

Meteorologists talk plenty about the dew point temperature during the summer, as it is a great indicator of humidity and a condition to watch when severe weather is possible. So what is it? The dew ...

We know proper indoor ventilation is key to reducing the spread of Covid-19. Now, a study by MIT researchers finds that indoor relative humidity may also influence transmission of the virus. Relative ...

The short answer is both terms are different and describe different things about moisture in the air. The dew point is another temperature value. It is the temperature air needs to cool to become ...
