dewpoint"(Or dewpoint temperature.) The temperature to which a given air parcel must be cooled at constant pressure and constant water vapor content in order for saturation to occur.
dewpoint temperature (or dewpoint)
Temperature to which an air parcel must be cooled at constant pressure and constant water vapor content in order for saturation of that air parcel with water vapor to occur with respect to a liquid water ...
Dewpoint Depression - the difference in degrees between the air temperature and the dewpoint temperature ...
DEWPOINT: The temperature to which the air must be cooled for water vapor to condense.
Dewpoint - If air is cooled to the dewpoint temperature without changing its pressure or moisture content, the relative humidity will increase to 100% and fog or dew may form.
DEWPOINT POOLING (DWPT PLG) - An area, usually along a surface front or trough, where there is a "pool" of higher dewpoints (or higher amounts of surface moisture).
Dewpoint Temperature to which air must be cooled (at constant pressure and constant water vapor content) to achieve saturation (if above 0 ·C or 32 ·F).

Dewpoint - A measure of atmospheric moisture. It is the temperature to which air must be cooled in order to reach saturation, assuming air pressure and moisture content are held constant.
Dew-Point
(Dewpoint Temperature) Temperature to which a volume of air must be cooled at constant pressure and constant moisture in order to reach saturation; any further cooling causes condensation.
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.
DewMoisture that has condensed on objects near the ground, whose temperatures have fallen below the dewpoint temperature.Dew Point(Abbrev. DWPT) - A measure of atmospheric moisture.
Fogs of all types originate when the temperature and dewpoint of the air become identical (or nearly so).
Instrument Shelter: A wooden box which houses various weather instruments for observing temperature, humidity, dewpoint.
This box has luvered sides for ventelation & prevents sunshine from entering.
An absolute humidity with a dewpoint of 14°C is chosen as a reference (this reference is adjusted a little with temperature).
Ridge used by itself refers to an area of high pressure, characterized by low dewpoints, sunny skies, and light winds. However, when combined with the word hostile it has a somewhat different meaning.

Dew - Moisture from water vapor in the air that has condensed on objects near the ground, whose temperatures have fallen below the dewpoint temperature.
The poleward air mass has an east-to-west component of air motion at low levels, is relatively cold (ex. Polar), and therefore dense, and has a relatively lower humidity value (lower dewpoint) than the 'opposing' air mass.
When the dry line retreats westward at night, the dew points will rise rapidly and the wind will shift from the west or southwest to the south or southeast. See Low Precipitation storm. It is also known as a "dewpoint front" or "dry front".
atmospheric moistureThe moisture content of the air as indicated by several measurements including relative humidity, specific humidity, dewpoint, vapor pressure, water vapor mixing ratio, and water vapor density; ...
