sinlat

.. py:function:: sinlat(fs)

   Returns the fieldset of the sine of the latitude of ``fs`` at each grid point.

   :param fs: input fieldset
   :type fs: :class:`Fieldset`
   :rtype: :class:`Fieldset`

   Missing values are retained, unaltered by the calculation.

   :Example:

      The following code shows how to compute the absolute vorticity from vorticity with :func:`sinlat`:

      .. code-block:: python

         import metview as mv
         import math

         omega = 2 * math.pi / 86400
         coriolis = 2 * omega * mv.sinlat(vort)
         absvort = vort + coriolis
