earthkit.meteo.thermo.array.potential_temperature
=================================================

.. py:function:: earthkit.meteo.thermo.array.potential_temperature(t, p)

   Compute the potential temperature.

   :param t: Temperature (K)
   :type t: :class:`number` or :class:`array-like`
   :param p: Pressure (Pa)
   :type p: :class:`number` or :class:`array-like`

   :returns: Potential temperature (K)
   :rtype: :class:`number` or :class:`array-like`

   The computation is based on the following formula [Wallace2006]_:

   .. math::

      \theta = t (\frac{10^{5}}{p})^{\kappa}

   with :math:`\kappa = R_{d}/c_{pd}` (see :data:`earthkit.meteo.constants.kappa`).
