Not wanting to be a smarty pants either but
Dew Point Temperature - Tdp
The
Dew Point is the temperature where water vapor starts to condense out of the air (the temperature at which air becomes completely saturated). Above this temperature the moisture stays in the air.
- if the dew-point temperature is close to the dry air temperature - the relative humidity is high
- if the dew point is well below the dry air temperature - the relative humidity is low
If moisture condenses on a cold bottle taken from the refrigerator the dew-point temperature of the air is above the temperature in the refrigerator.
The Dew Point temperature is always lower than the Dry Bulb temperature and will be identical with 100% relative humidity (the air is at the saturation line). As air temperature changes the Dew Point tends to remain constant unless water is added or removed from the air.
The Dew Point temperature can be measured by filling a metal can with water and some ice cubes. Stir by a thermometer and watch the outside of the can. When the vapor in the air starts to condensate on the outside of the can, the temperature on the thermometer is pretty close to the dew point of the actual air.
the dew point is dependent on the relative humidity of the air and its temperature - but I know what you meant
However, I completely agree with your post otherwise
