<div>Hi all</div>
<div> </div>
<div>I am trying to draw a diagram to show vertical meridional circulation. I wrote a simple script to draw it: </div>
<div><span lang="EN"></span> </div>
<div><span lang="EN">'sdfopen D:\<a href="http://vcomp_month.nc">vcomp_month.nc</a>'</span></div>
<div>
<p>'sdfopen D:\<a href="http://ucomp_month.nc">ucomp_month.nc</a>'</p>
<p>'set t 1'</p>
<p>'set gxout vector'</p>
<p>'set lev 1000 300'</p>
<p>'set lat 0 60'</p>
<p>'define a = ave(vcomp.1,lon=100,lon=130)'</p>
<p>'define b = ave(ucomp.2,lon=100,lon=130)'</p>
<p>'d a;b'</p>
<p> </p>
<p>It shows an error as follows:</p>
<p>"Operation error: Invalid dimension environment</p>
<p>Looping dimension does not vary"</p>
<p>Does any body know where I went wrong? I am using verion 2.9 on windows xp</p>
<p>Thanks</p>
