A researcher at the Max Planck Institute for Chemistry in Mainz, Germany, has suggested a very simple formula for converting between the relative humidity and the dew point temperature without needing ...

It’s not too hard to find the words to describe New Hampshire’s weather over the past few days. Some words come to mind like oppressive, sticky, tropical, clammy and sweaty.Simply put, it’s humid. But ...

On a calm, clear night, the ground cools very efficiently by radiating heat back into the atmosphere. This lowers the temperature of the air near the ground. By morning, temperatures will most often ...

Relative humidity and dew point both give us an idea of the amount of moisture in the atmosphere; however, only dew point is a true measurement of the atmospheric moisture. Relative humidity is ...

We’ve recently received several reader requests asking us how to calculate relative humidity if the temperature and dew point are known. Relative humidity is the ratio (expressed as a percentage) of ...

The dew point is the temperature that the air would have to be cooled to (at constant pressure) in order to reach saturation. As the temperature drops to the dew point, water vapor molecules condense.

We always seem to drop the first name of “relative humidity” to just plain old “humidity”. That doesn’t sound like a big deal. People I know call me Zollitsch all the time. In fact my high school ...

A News 3 viewer recently emailed the First Warning Storm Team, asking us about the difference between relative humidity and the dew point. We use these weather terms in our forecasts to determine how ...

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 ...

Relative humidity and dew point are often mistaken for the same thing and can be sources of confusion. But what are the differences between the two, and which is more relevant in everyday life?

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 ...

Humidity can make or break a summer day. A sunny day with a temperature of 85 degrees can feel pleasant when the humidity stays low, but once the humidity cranks up, that same day can become ...
