to display surface wind gust speeds using the GFS datasets (self-describing

servers?</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=616331222-01092013>I've tried all sorts
of different combinations such as "d mag(ugrd10m;vgrd10m;gustssfc)", "d
gustssfc", etc as well as the GFS data from monsoondata but no
luck. However, some websites offer GFS wind gust speed charts (e.g. <A

appear in the datasets' </SPAN></FONT><FONT face=Arial size=2><SPAN
