<p>Hi all,</p>
<p> </p>
<p>I have a couple of questions, firstly I am trying get the mean run in a spaghetti graph of the GEFS but I seem to keep getting the control run. Here is the script:</p>
<p>'set t 1 65'<br>'set e 1'<br>'set csmooth on'<br>'set cmark 0'<br>'set lat 53';'set lon -2.23'<br>'set vrange -30 30'<br>'define t850=tmpprs(lev=850)-273.16'<br>'define ensmean=ave(t850,e=1,e=21)'<br>'set gxout line'<br>'set ccolor 2'<br>'set cthick 8'<br>'d ensmean'</p>
<p> </p>
<p>Second question, using the GFS how do I produce anomaly charts with this script, im not sure how to define it.....</p>
<p>'set t 'i<br>'set grads off'<br>'set csmooth on'<br>'define geopotdam = hgtprs(lev=500)/10'<br>'color -gxout shaded -30 30 1 -kind blue->white->red-> -xcbar 10.1 10.3 0.7 7.74 -fs 10'</p>
<p> </p>
<p>Regards,</p><span class="HOEnZb"><font color="#888888">
