def coriolis_parameter(latitude):
    r"""Calculate the coriolis parameter at each point.

    The implementation uses the formula outlined in [Hobbs1977]_ pg.370-371.

    Parameters
    ----------
    latitude : array_like
        Latitude at each point

    Returns
    -------
    `pint.Quantity`
        The corresponding coriolis force at each point
