[gradsusr] How to plot the atmospheric cells

[kalyan chakravarthy]

Dear David,
Thanks for your help
I have tried to plot the Hadley cell with the suggestions you made
still having problem with it

 Set lat -30 30
 set t 1(for example June)
 set lev 1000 100
 d mean(vwnd,lon=50,lon=100);mean(omega.2*1.0e3,lon=50,lon=100)

Says: Invalid Dimension Environment

Can you please tell what is the problem...
Thanking you..
