Hi Jung-Hoon,
The email client that I was using this morning mistakingly showed that
you didn't have an attachment. My mistake. I came up with an example NCL
script that shows you how to make use of NCL's font tables to create
PIREP symbols. You can see the font tables here:
http://www.ncl.ucar.edu/Document/Graphics/font_tables.shtml
There are a number of great examples on how to access the various
characters here:
http://www.ncl.ucar.edu/Applications/eqn.shtml
The script shown here creates the attached plot. For most symbols I had
to combine some characters, as most PIREP symbols are not available from
any font table.

While I plotted turbulence indices such as Ri (Richardson number), TI (Turbulence Index; Ellord and Knapp 1992) and so on, I would like to overlay the turbulence icons observed and reported by PIREPs (pilot reports) using NCL. I couldn't find how can I overlay turbulence icons (light, moderate, severe), even though I tried to find on the NCL web page. Is there something to solve this problem ? Please, let me know, if you have the solutions.
