earthkit.meteo.thermo.array.relative_humidity_from_specific_humidity
====================================================================

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

   Compute the relative humidity from specific humidity.

   :param t: Temperature (K)
   :type t: :class:`array-like`
   :param q: Specific humidity (kg/kg)
   :type q: :class:`array-like`
   :param p: Pressure (Pa)
   :type p: :class:`array-like`

   :returns: Relative humidity (%)
   :rtype: :class:`array-like`

   The computation is based on the following formula:

   .. math::

       r = 100 \frac {e(q, p)}{e_{msat}(t)}

   where:

       * :math:`e` is the vapour pressure (see :func:`vapour_pressure_from_specific_humidity`)
       * :math:`e_{msat}` is the :func:`saturation_vapour_pressure` based on the "mixed" phase
