Observed Dew Point Temperature
indicates the amount of moisture in the air
The value highlighted in yellow located
in the lower left corner (in the diagram above) is the
dew point temperature in degrees
In this example, the reported dew point temperature is 58 degrees.
Dew points indicate the amount moisture in the air.
The higher the dew points, the higher the moisture content of the
air at a given temperature.
Dew point temperature
is defined as the temperature to which the air
would have to cool (at constant pressure and constant water vapor content)
in order to
reach saturation. A state of saturation exists when the air is holding the
maximum amount of water vapor possible at the existing temperature and
