Have you ever wondered why meteorologists on TV focus on the dewpoint temperature and not relative humidity? Or, have you ...

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 ...

Summer is here, and heat and humidity have arrived.

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 that ...

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 ...

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 ...

When a meteorologist or a dedicated weather weenie hears the “90-degree heat with 90 percent humidity” refrain he or she winces and wants to say something like, “It never happens here. Let me teach ...

Dew point is the temperature at which the air becomes “saturated” – in other words, it is holding all the water vapor it possibly can. If the temperature and the dew point equal each other, the water ...
