The objective of these GrADS scripts is to plot
the percentage of horizontal and vertical modes 
energy interaction,

1 - The file dir.cfg contains directories used by
    the GrADS scripts. It is generate by
    ${dirhome}/Config/Create_gs_dir_cfg
    after define yours own dirhome and dirdata at
    ${dirhome}/Config/Config_Dir

2 - The GrADS script percphvint.gs is used to
    plot the horizontal Field of the percentage of
    horizontal and vertical modes energy interaction
    at a level or at a vertical layer
    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
    and vertical layers:
    a) lower troposphere,
    b) medium troposphere,
    c) upper troposphere,
    d) stratosphere and up,
    e) bottom troposphere,
    f) center troposphere and
    g) hight troposphere
    Usage, inside the GrADS aplicativo (grads) use
    percphvint -h
    to see the arguments and default, and
    percphvint caso epoca casestudy mean Mmax var pfa pfb area crssct hili cnt stl
    to generate the percentage of horizontal and vertical 
    modes energy interaction figure.
    Must use grads landscape.

3 - The GrADS script percphvintt.gs is used to
    plot the horizontal Field of the sum of percentage
    of horizontal and vertical modes energy interaction
    and its reverse (e.g. rbkv01 and kvrb01)
    at a level or at a vertical layer
    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
    and vertical layers:
    a) lower troposphere,
    b) medium troposphere,
    c) upper troposphere,
    d) stratosphere and up,
    e) bottom troposphere,
    f) center troposphere and
    g) hight troposphere
    Usage, inside the GrADS aplicativo (grads) use
    percphvintt -h
    to see the arguments and default, and
    percphvintt caso epoca var pfa pfb area cnt stl hili
    percphvintt caso epoca casestudy mean Mmax var1 pfa pfb area crssct hili cnt stl
    to generate the sum of percentage of horizontal and 
    vertical modes energy interaction and its reverse figure.
    Must use grads landscape.

4 - The Grads script xsecint.gs is used to plot a
    vertical cross section of the energy interaction
    or its porcentage of energy for selected two points.
    (See CrossSections.gs at ${dirhome}/Config)
    Usage, inside the GrADS aplicativo (grads) use
    xsecint -h
    to see the arguments and default, and
    xsecint caso epoca casestudy mean Mmax ewv pt dp
    to generate the vertical cross-section field
    of the energy interaction or its percentage.
    Must be runned under grads -p

Obs:

    1 - The GrADS scripts rainhvia.gs, rainhvib.gs
        and rainhvi.gs are specific for the 
        case study RainRS.

    2 - The GrADS scripts difintkv0rb1HS.gs, 
        difintrb0kv1HS.gs, totintkv0rb1HS.gs and 
        totintrb0kv1HS.gs are specific for the
        case study SaoSebatiao.

    3 - The GrADS scripts totintkv0rb1HSclm.gs
        and totintrb0kv1HSclm.gs are specific for 
        the case study SaoSebClm.

    4 - GrADS script saoseb.gs run all scripts for the cases
        studies SaoSebastiao and SaoSebClm for the default values.
