potential_temperature

metpy.calc.potential_temperature(pressure, temperature)

Calculate the potential temperature.

Uses the Poisson equation to calculation the potential temperature given pressure and temperature.

Parameters:

• pressure (pint.Quantity) – Total atmospheric pressure

• temperature (pint.Quantity) – Air temperature

Returns:

pint.Quantity – Potential temperature corresponding to the temperature and pressure
