It is based on an algorithm called ggtheta developed by Leo<BR>Clarke many years ago here at Fleet Numerical. I have a fortran routine<BR>that implements the basic technique, but I have not made the changes<BR>suggested in the article. Let me know if you are interested.<BR><BR>Michael Sestak<BR>Fleet Numerical Meteorology and Oceanography Center<BR>Monterey, CA<BR><BR>-----Original Message-----<BR>From: Evgeny Himmelreich [mailto:evgenyh@IMS.GOV.IL]<BR>Sent: Tuesday, December 28, 2004 5:23 AM<BR>To: GRADSUSR@LIST.CINECA.IT<BR>Subject: Automatic front drawing alorithm<BR><BR><BR>Hi everybody!<BR><BR>Does anyone knows the algorithm (or have
