What does a low dew point indicate about the moisture content of air?
The dewpoint is the temperature to which the air must be cooled to become saturated. A lower dewpoint, as in winter, indicates there is less moisture in the air, so the air must be cooled farther before it will become saturated with water. Dewpoint is a combination of many factors, including temperature, humidity, and pressure.
What is the temperature to which air must cool to be saturated?
Dew pointThe dew point is the temperature to which air must cool to be saturated.
The upward movement of air in the atmosphere generally causes the temperature of that air to?
Decrease and become closer to the dewpoint. :-)
How does humidity change over 24 hours?
Cold air cannot hold as much water vapor as warm air. As temperature drops relative humidity rises. Absolute humidity remains constant until the dewpoint temperature is reached, then decreases with temperature as water precipitates out of the air. Below the dewpoint temperature relative humidity remains constant at 100%.
What is the relation between altitude of a base cloud and the temperature of the air at that altitude?
The base of the cloud occurs at the dewpoint temperature of the airmass. See: http://www.csgnetwork.com/estcloudbasecalc.html
What term refers to the temperature at which the relative humidity is 100?
That would be "dewpoint"...When the air temperature falls to the dewpoint (or dewpoint rises to the air temperature), then you have 100% relative humidity.
Are temperature and dewpoint related?
no
What is it called when temperature is saturated and condensation begins?
It is called the dewpoint.
What is the definition of dewpoint?
The temperature at which air becomes saturated and produces dew
What is meant by the term dewpoint''''?
The temperature to which air must be cooled to become saturated.

What is the temperature to which air must cool to be saturated?
Dew pointThe dew point is the temperature to which air must cool to be saturated.
Is humidity a percentage?
Yes, humidity is expressed as a percentage. When the dewpoint and the humidity are nearly the exactly the same or exactly the same as the air temperature, you'll have fog. The higher the dewpoint, the more humid it will feel.
The upward movement of air in the atmosphere generally causes the temperature of that air to?
Decrease and become closer to the dewpoint. :-)
What is dew point and how do you know the temperature has reached its dew point?
If its over 50 u have reached dewpoint.
How does humidity change over 24 hours?

Absolute humidity remains constant until the dewpoint temperature is reached, then decreases with temperature as water precipitates out of the air.

What type of air has a realative humidity of 100 percent?
That would be "dewpoint"...When the air temperature falls to the dewpoint (or dewpoint rises to the air temperature), then you have 100% relative humidity.
