Due April 21, 2004

1. Using the Gempak program gdcntr, create a map a 500 mb of heights and absolute vorticity. Using the contour fill capability of gdcntr, use vorticity and plot its contours as filled contours and use height as standard contour lines.

1. For data, use either the eta, ngm, avn or nogaps models.
2. Loop at least 5 forecast times.
3. Comment on where you might expect to find interesting weather based on Vorticity discussions from lectures in class.
   
   
   
   
   Place your plot on your website and e-mail laufers@ou.edu the url using Comuter Assignment 12 as the subject line.
   
   Hints:
   • Plot contour fills first as they will cover any work previously done.
   • To get the nice "X" at the center of the vorticity maximum use the following:
   • HILO = 2;/X/15-500/30;30/y
     HLSYM = 2;1.5//21//hw
   • Did I mention contour fills should be plotted first?
   • This would make a good script.
