Wind vector arrowsFor station data, these additional graphics output types are also available:
findstn
Finds nearest stationmodel

Plots a mark at station location that is colorized by data valuetserbarb
Time series of wind barbs at a point (1-D)tserwx
Time series of weather symbols at a point (1-D)value

Plots weather symbols at station,
controlled by set wxopt
vector, stream,
and barb
,
the plotting routines need two result grids, where the first result grid is
treated as the U component, and the second result grid is treated as the V
component. These two result grids are provided with the display
command by entering two expressions separated by a semicolon:
display u ; v
display ave(u,t=1,t=10) ; ave(v,t=1,t=10)
vector
and
stream
, you can specify a third result grid that will be used to
colorize the vectors or streamlines:
display u ; v ; mag(u,v)
display u ; v ; hcurl(u,v)
wxsym
, each value at a station
location is assumed to be a wx symbol code number. To see a chart of
all available wx symbols and their corresponding code numbers, run the
sample script wxsym.gs
.
findstn
requires three arguments to
be provided with the display
command. The first argument
is a station data expression. The 2nd and 3rd arguments are the X and Y screen
coordinates of the of the desired search location. GrADS will find the station
closest to the specified X and Y position, and print its stid, lon, and lat.
This graphics output type should only be used when X and Y are the varying
dimensions and AFTER a regular display command (that results in graphics output)
is entered.
stnmark
, the size and style of
the mark are controled by set digsiz
and set cmark
. To turn off rainbow
colorizing and use a single color instead, use set
ccolor
