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.

(WHTM) — When temperatures rise, sometimes the air can feel dry and comfortable. But, sometimes it can feel downright tropical outside. This is caused by moisture in the air and it makes the air ...

CORPUS CHRISTI, Texas — You see it all the time. The humidity is 100%! So humid! Air you can wear! While that may be true *at times*, it doesn't paint the full picture. When humidity is expressed as a ...

why do meteorologists use dew point rather than relative humidity to describe the uncomfortableness or oppressiveness of an air mass? Dew point is the temperature at which the air becomes “saturated” ...

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 ...

GREENSBORO, N.C. — Two common weather terms you'll hear many times in the warmer part of the year are "dew point" and "relative humidity". While both relate to moisture in the air and the "stickiness" ...

FARGO — Cool fall weather is an excellent time for a further examination of relative humidity. It is common during cool, damp, cloudy weather for the relative humidity to hover around 100%, yet your ...

KNOXVILLE, Tenn. — As we head into the spring and summer, meteorologists are going to talk more about humidity and dew point. But, what’s the difference? You might be used to checking the humidity ...

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, ...

Dew point, a direct measure of atmospheric moisture, is a much better indicator of discomfort than relative humidity. It is a conservative feature, meaning it remains reasonably constant during the ...

I know in Houston, we hear the term humidity which is used to correlate to how muggy it may feel outside. But what actually is humidity and what does it represent? Humidity is the measurement of water ...
