earthkit.meteo.wind.array.coriolis
==================================

.. py:function:: earthkit.meteo.wind.array.coriolis(lat)

   Compute the Coriolis parameter.

   :param lat: Latitude (degrees)
   :type lat: :class:`array-like`

   :returns: The Coriolis parameter (:math:`s^{-1}`)
   :rtype: :class:`array-like`

   The Coriolis parameter is defined by the following formula:

   .. math::

       f = 2 \Omega sin(\phi)

   where :math:`\Omega` is the rotation rate of Earth
   (see :data:`earthkit.meteo.constants.omega`) and :math:`\phi` is the latitude.
