Calculate equivalent potential temperature.
This calculation must be given an air parcel’s pressure, temperature, and dewpoint.
The implementation uses the formula outlined in [Bolton1980]:
First, the LCL temperature is calculated:
Which is then used to calculate the potential temperature at the LCL:
Both of these are used to calculate the final equivalent potential temperature:
pressure (pint.Quantity) – Total atmospheric pressure
temperature (pint.Quantity) – Temperature of parcel
dewpoint (pint.Quantity) – Dewpoint of parcel
pint.Quantity – Equivalent potential temperature of the parcel
[Bolton1980] formula for Theta-e is used, since according to
[DaviesJones2009] it is the most accurate non-iterative formulation
