NAME

       WMBARB - plots wind barbs.

SYNOPSIS

       CALL WMBARB (X,Y,U,V)

C-BINDING SYNOPSIS

       #include <ncarg/gks.h>

       void c_wmbarb(float x, float y, float u, float v)

DESCRIPTION

       X           (Real,  Input)  -  An X coordinate (specified in world coordinates) of a point that specifies
                   the position of the base of a wind barb.

       Y           (Real, Input) - A Y coordinate (specified in world coordinates) of a point that specifies the
                   position of the base of a wind barb.

       U           (Real, Input) - The X component of a wind vector.

       V           (Real, Input) - The Y component of a wind vector.

USAGE

       The angle at which the wind barb is drawn is determined by the vector (U,V) and  the  magnitude  of  that
       vector  denotes  the  wind speed in knots.  Set the values for the appropriate internal parameters before
       calling WMBARB to produce the wind barb.  The internal parameters that control  the  appearance  of  wind
       barbs are: COL, WBA, WBD, WBF, WBS, WBT.

ACCESS

       To  use WMBARB or c_wmbarb, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in
       that order.
