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 – The potential temperature corresponding to the temperature and pressure.
