The objective of these GrADS scripts is to plot
some chacteristics of the horizontal decomposition.

1 - The file dir.cfg contains directories used by
    the GrADS scripts. It is generate by
    ${dirhome}/Config/Create_gs_dir_cfg

    ${dirhome}/Config/Config_Dir

2 - The Grads script etzmh.gs is used to plot the
    the meridional profile of the zonal mean

    percentage of horizontal modes (Rossby, Kelvin, 
    mixed, gravity west and gravity east) energy figures.

5 - The Grads script perchint.gs is used to plot the
    the horizontal field of the percentage of
    horizontal modes (Rossby, Kelvin, mixed,
    gravity west and gravity east) energy interaction
    for the following classes:
    Class 0 : Hn >= 600 m
    Class 1 : 100 m (90) =< Hn < 600 m
    Class 2 : 10 m =< Hn < 100 m
    Class 3 : 1 m =< Hn < 10 m
    Class 4 : Hn < 1 m
    Usage, inside the GrADS aplicativo (grads) use
    perchint -h
    to see the arguments and default, and
    perchint caso epoca casestudy mean Mmax area crssct pl hili stlp
    to generate the horizontal field of the percentage 
    of horizontal modes (Rossby, Kelvin, mixed, gravity west 
    and gravity east) energy interaction figures.
    Must be runned under grads landscape.

6 - The Grads script perchintt.gs is used to plot the
    the horizontal field of the percentage of
    horizontal modes (Rossby, Kelvin, mixed,
    gravity west and gravity east) energy interaction
    for casA and casb for the classes kci to kcf:
    Class 0 : Hn >= 600 m
    Class 1 : 100 m (90) =< Hn < 600 m
    Class 2 : 10 m =< Hn < 100 m
    Class 3 : 1 m =< Hn < 10 m
    Class 4 : Hn < 1 m
    Usage, inside the GrADS aplicativo (grads) use
    perchintt -h
    to see the arguments and default, and
    perchintt caso epoca casestudy mean Mmax area kci kcf casA casB crssct pl hili stlp
    to generate the horizontal field of the percentage 
    of horizontal modes (Rossby, Kelvin, mixed, gravity west 
    and gravity east) energy interaction for casA and casB 
    for the classe kci to kcf figures.
    Must be runned under grads landscape.

7 - The Grads script percht.gs is used to plot the
    the horizontal field of the percentage of
    horizontal modes (Rossby, Kelvin, mixed,
    gravity west and gravity east) total energy
    for a given horizontal model and for classes
    kci to kcf:
    Class 0 : Hn >= 600 m
    Class 1 : 100 m (90) =< Hn < 600 m
    Class 2 : 10 m =< Hn < 100 m
    Class 3 : 1 m =< Hn < 10 m
    Class 4 : Hn < 1 m
