<DIV>Hi GrADS users,</DIV> <DIV> </DIV> <DIV>When I plotted the 'Primary Wave Direction' from both FNMOC WW3 and NOAA WW3 the other day, I've found some discontinuity over the Indian Ocean for NOAA WW3 (FNMOC WW3 seems OK). Anyone knows why this occurs, I used same script to produce those two charts (see attachments).</DIV> <DIV> </DIV> <DIV>Thanks in advance.</DIV> <DIV> </DIV> <DIV>Hong Wang</DIV> <DIV>Senior Marine Meteorologist</DIV> <DIV>Fugro GEOS.</DIV><BR><BR><DIV class=MsoNormal align=left><SPAN><FONT face="Verdana, Helvetica"><FONT size=4><IMG style="WIDTH: 42px; HEIGHT: 53px" height=113 alt=anemometer hspace=10 src="http://media.nasaexplores.com/lessons/04-005/images/k4anemometer.jpg" width=118 align=center vspace=10><FONT color=#407f00><FONT color=#609a9f>©</FONT><FONT face="comic sans ms"><EM><FONT color=#609a9f><STRONG>OZ</STRONG>weatherman</FONT> </EM></FONT></FONT></FONT></FONT></SPAN></DIV><p>
