.. py:function:: earthkit.meteo.thermo.array.wet_bulb_temperature_from_dewpoint(t, td, p, ept_method='ifs', t_method='bisect')

   Compute the pseudo adiabatic wet bulb temperature from dewpoint.

   :param t: Temperature (K)
   :type t: :class:`number` or :class:`array-like`
   :param td: Dewpoint (K)
   :type td: :class:`number` or :class:`array-like`
   :param p: Pressure (Pa)
   :type p: :class:`number` or :class:`array-like`
   :param ept_method: Specifies the computation method for the equivalent potential temperature.
                      The possible values are: "ifs", "bolton35", "bolton39".
                      (See :func:`ept_from_dewpoint` for details.)
   :type ept_method: :class:`str`, *optional*
   :param t_method: Specifies the method to find the temperature along the moist adiabat defined
                    by the equivalent potential temperature. The possible values are as follows:

                    * "bisect": :func:`temperature_on_moist_adiabat` with ``t_method`` = "bisect" is used
                    * "newton": :func:`temperature_on_moist_adiabat` with ``t_method`` = "newton" is used
   :type t_method: :class:`str`, *optional*

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

   The computation is based on Normand's rule [Wallace2006]_ (Chapter 3.5.6):

   * first the equivalent potential temperature is computed with the given
     ``ept_method`` (using :func:`ept_from_dewpoint`). This defines the moist adiabat.
   * then the wet bulb potential temperature is determined as the temperature at
     pressure ``p`` on the moist adiabat with the given ``t_method``.
