earthkit.meteo.thermo.array.virtual_temperature
===============================================

.. py:function:: earthkit.meteo.thermo.array.virtual_temperature(t, q)

   Compute the virtual temperature from temperature and specific humidity.

   :param t: Temperature (K)s
   :type t: :class:`number` or :class:`array-like`
   :param q: Specific humidity (kg/kg)
   :type q: :class:`number` or :class:`array-like`

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

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

   .. math::

       t_{v} = t (1 + \frac{1 - \epsilon}{\epsilon} q)

   with :math:`\epsilon = R_{d}/R_{v}` (see :data:`earthkit.meteo.constants.epsilon`).
