Dew formation is a natural process in which water vapour condenses on cool surfaces, typically during clear, calm nights when radiative cooling lowers surface temperatures below the dew point. This ...

NORFOLK, Va. — The old saying goes “it’s not the heat, it’s the humidity!” And while that may be true, it’s only half of the story. It’s the “dew point” that really matters. But what is the dew point?

Radiational cooling can greatly affect how big of a temperature swing we see between night and day.

Before you step outside, you may want to know how humid, or "sticky" it feels. That comes down to knowing the dew point. Dew point is more commonly discussed in the summertime and is a good measure of ...

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 ...
