what does dew point mean?

Answer 1

This is the temp. where condensation of vapor occurs.

Answer 2

The dew point is the temperature to which a given parcel of air must be cooled, at constant barometric pressure, for water vapor to condense into water. The condensed water is called dew. The dew point is a saturation point. When the dew point temperature falls below freezing it is often called the frost point, as the water vapor no longer creates dew but instead creates frost or hoarfrost by deposition. The dew point is associated with relative humidity. A high relative humidity indicates that the dew point is closer to the current air temperature. Relative humidity of 100% indicates the dew point is equal to the current temperature and the air is maximally saturated with water. When the dew point remains constant and temperature increases, relative humidity will decrease.[1] At a given barometric pressure, independent of temperature, the dew point indicates the mole fraction of water vapor in the air, and therefore determines the specific humidity of the air. The dew point is an important statistic for general aviation pilots, as it is used to calculate the likelihood of carburetor icing and fog, and estimate the height of the cloud base.

Answer 3

The dew point or dewpoint of a given parcel of air is the temperature to which the parcel must be cooled, at constant barometric pressure, for the water vapor component to condense into water, called dew.

Answer 4

There is a good answer for

What Exactly Is The Dew Point?

in the following website.

Answer 5

Dew point is the temperature at or below which dew or liquid water will drop out of the air.

Answer 6

The dew point is 100% relative humidity. It is the point that the air is saturated with water.

The temperature that this happens at is relative to the amount of water vapor present, hence the term relative humidity.
