temperature_from_potential_temperature

metpy.calc.temperature_from_potential_temperature(pressure, potential_temperature)

Calculate the temperature from a given potential temperature.

Uses the inverse of the Poisson equation to calculate the temperature from a given potential temperature at a specific pressure level.

Parameters

• pressure (pint.Quantity) – Total atmospheric pressure

• potential_temperature (pint.Quantity) – Potential temperature

Returns

pint.Quantity – Temperature corresponding to the potential temperature and pressure

dry_lapse, potential_temperature

Notes

Formula:

\[T = \Theta (P / P_0)^\kappa\]

Examples

>>> from metpy.units import units
>>> from metpy.calc import temperature_from_potential_temperature
>>> # potential temperature
>>> theta = np.array([ 286.12859679, 288.22362587]) * units.kelvin
>>> p = 850 * units.mbar
>>> T = temperature_from_potential_temperature(p, theta)

Changed in version 1.0: Renamed theta parameter to potential_temperature
