The formula to calculate Dew Point Depression is:
\[ \text{dpd} = T - \text{dpt} \]
Dewpoint Depression is the difference between the temperature and dew point temperature at a certain height in the atmosphere. Temperature is the degree or intensity of heat present in a substance or object. Dewpoint 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.
Let's assume the following values:
Using the formula:
\[ \text{dpd} = 85 - 100 = -15 \, \text{Kelvin} \]
The Dew Point Depression is approximately -15 Kelvin.
