Dew point/relative humidity questions come up fairly often and this is a good one. Water vapor in the atmosphere is pretty important for deep-sky observing and photography. The atmosphere can only ...

TUCSON, Ariz. (KGUN) — The First Warning weather team often refers to dew point and humidity. Most people know these terms have something to do with moisture, but a lot of people don’t really ...

Noel Kirkpatrick is an editor and writer based in Tacoma, Washington. He covers many topics, including animals, science, and the environment. Complaining about the humidity is a go-to conversation ...

Fog can form when the humidity is less than 100 percent, but it generally is in the range of 95 to 100 percent when fog is present. Occasionally, though rarely, the relative humidity will be 100 ...

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 ...

This week, there has been lots of discussion regarding the dew point and how it relates to humidity. While most of us have probably heard of the dew point, do you actually know what it is?

Let’s first state the obvious. Most techs are intimidated by Psychrometric charts and Mollier diagrams, we just are. While there are some pretty complicated formulas that back up these diagrams, using ...

The dew point is the temperature at which air is saturated with water vapor, which is the gaseous state of water. When air has reached the dew-point temperature at a particular pressure, the water ...

What does the dew point measure? Mike Moss: The number of a dew point, for example 62, represents the temperature at which a given air mass would be saturated with water vapor, so that any additional ...

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 ...
