NCL Graphics: Wind Rose
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/wind_rose.ncl"
A wind rose displays the frequency (percentage) of wind directions for
a specific location over a specifed period of time. The wind rose
created by NCL's wind rose procedure is circular with each circle
representing the percentage of time the wind blows from a
particular direction. The mean wind speed is printed at the end of
each directional line. FInally, overall statistics for the entire
data sample are included in the title.
NOTE: This is a donated function. Users may have to modify the code
themselves for special effects. The code is not necessarily supported by
the NCL Team. Questions to ncl-talk@ucar.edu may or may not be answered.
