climatologyMapWindStressCurl
============================

An analysis task for plotting maps of wind stress curl.

Component and Tags::

  component: ocean
  tags: climatology, horizontalMap, windStressCurl, publicObs

Configuration Options
---------------------

The following configuration options are available for this task::

    [climatologyMapWindStressCurl]
    ## options related to plotting horizontally remapped climatologies of
    ## wind stress curl against control model results

    # colormap for model/observations
    colormapNameResult = cmo.curl
    # whether the colormap is indexed or continuous
    colormapTypeResult = continuous
    # color indices into colormapName for filled contours
    # the type of norm used in the colormap
    normTypeResult = linear
    # A dictionary with keywords for the norm
    normArgsResult = {'vmin': -1e-6, 'vmax': 1e-6}

    # colormap for differences
    colormapNameDifference = cmo.balance
    # whether the colormap is indexed or continuous
    colormapTypeDifference = continuous
    # the type of norm used in the colormap
    normTypeDifference = linear
    # A dictionary with keywords for the norm
    normArgsDifference = {'vmin': -2e-7, 'vmax': 2e-7}

    # Months or seasons to plot (Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct,
    # Nov, Dec, JFM, AMJ, JAS, OND, ANN)
    seasons =  ['ANN']

    # comparison grid(s) on which to plot analysis
    comparisonGrids = ['latlon']

For analysis focused on polar regions (using the ``--polar_regions`` flag),
the following config options add Arctic and Antarctic comparison grids::

    [climatologyMapWindStressCurl]
    ## options related to plotting horizontally remapped climatologies of
    ## wind stress curl against control model results

    # comparison grid(s) on which to plot analysis
    comparisonGrids = ['latlon', 'arctic_extended', 'antarctic_extended']
