ROCHESTER, N.Y. (WHEC) – We are going to talk directly to the weather geeks. Today we look at the difference between dew point and relative humidity. The dew point is basically a simple concept. It is ...

When referring to the mugginess of the air, meteorologists will point to dew point rather than relative humidity. Relative humidity is indeed a measure of how much moisture is in the air relative to ...

Editor’s note: The KOIN 6 Weather team is presenting weather and science lessons to help serve our teachers and students. Click here for more lessons. PORTLAND, Ore. (KOIN) – I would like to preface ...

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 ...

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 ...

Dew point and relative humidity, two terms that have floated around many weather forecasts over the years. What exactly do they mean and when are they best used to describe the conditions outside? Let ...

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.

The dew point is the temperature to which air much be cooled for it to become saturated with water vapor. However, there is nothing special about subzero temperatures. They are a peculiarity of the ...

Dew point is a common phrase during the summertime, but what exactly is it? Put simply, the dew point is the temperature the air needs to cool to to become fully saturated. On any given day, there is ...

I took a phone call the other day asking why I don’t use the “Relative” Humidity number on my weathercasts like others, but use the Dew Point, instead. Then I wondered if the person on the other end ...

ROCHESTER, N.Y. – This time of the year it is especially important that we effectively communicate the amount of moisture in the atmosphere on any given day. There are different ways of doing this, ...

I've long wondered whether dew point or relative humidity is more important for good seeing. Which would be better: a cool night with lower dew point but higher humidity, or a warm night with higher ...
