earthkit.meteo.wind.array.w_from_omega
======================================

.. py:function:: earthkit.meteo.wind.array.w_from_omega(omega, t, p)

   Compute the hydrostatic vertical velocity from pressure velocity, temperature and pressure.

   :param omega: Hydrostatic pressure velocity (Pa/s)
   :type omega: :class:`array-like`
   :param t: Temperature (K)
   :type t: :class:`array-like`
   :param p: Pressure (Pa)
   :type p: :class:`array-like`

   :returns: Hydrostatic vertical velocity (m/s)
   :rtype: :class:`array-like`

   The computation is based on the following hydrostatic formula:

   .. math::

       w = - \frac{\omega\; t R_{d}}{p g}

   where

       * :math:`R_{d}` is the specific gas constant for dry air (see :data:`earthkit.meteo.constants.Rd`).
       * :math:`g` is the gravitational acceleration (see :data:`earthkit.meteo.constants.g`)
