earthkit.meteo.thermo.array.pressure_on_dry_adiabat
===================================================

.. py:function:: earthkit.meteo.thermo.array.pressure_on_dry_adiabat(t, t_def, p_def)

   Compute the pressure on a dry adiabat.

   :param t: Temperature on the dry adiabat (K)
   :type t: :class:`number` or :class:`array-like`
   :param t_def: Temperature defining the dry adiabat (K)
   :type t_def: :class:`number` or :class:`array-like`
   :param p_def: Pressure defining the dry adiabat (Pa)
   :type p_def: :class:`number` or :class:`array-like`

   :returns: Pressure on the dry adiabat (Pa)
   :rtype: :class:`number` or :class:`array-like`

   The computation is based on the following formula:

   .. math::

      p = p_{def} (\frac{t}{t_{def}})^{\frac{1}{\kappa}}

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