Hi kaikombo, 

Here are a few script changes you should make: 


1. remove the lines 'set x 1 144' and 'set y 1 73' 
2. change 'set lon 0 360' to 'set lon -180 180' 
3. move your sdfopen commands (uwnd and vwnd) outside the while loop--it's unnecessary to open these files every time through the loop 
4. remove the 'reinit' command that's inside the while loop 
5. remove 'disable sdfwrite', this is an invalid command 


Best regards,

I have write the filed for the vorticity at each level using the NCEP u and v winds. 
but when I plot these files at the lon and lat of my interest it leaves a verticle strip at lon 0 
any one can help on I how to remove this strip?. 
I have attached the image which I have plotted. 
this is my script 
'reinit' 
'c' 
lev.1=925 
lev.2=850 
lev.3=700 
lev.4=600 
lev.5=500 
lev.6=400 
lev.7=300 
lev.8=250 
lev.9=200 
lev.10=150 
lev.11=100 
levcount=1 
while(levcount<=11) 
lev=lev.levcount 
say lev 
'sdfopen d:/vorticity/uwnd.mon.mean.nc' 
'sdfopen d:/vorticity/vwnd.mon.mean.nc' 
'set lon 0 360' 
'set lat -90 90' 
'set t 1 778' 
'set lev 'lev 
'set x 1 144' 
'set y 1 73' 
'vort=hcurl(uwnd,vwnd.2)' 
'set sdfwrite d:/vorticity2/'lev'_vorty.nc' 
'sdfwrite vort' 
'reinit' 
levcount=levcount+1 
endwhile 
'disable sdfwrite' 
'reinit' 

sdfopen d:/vorticity2/850_vorty.nc 
set lon -70 120

Dear GrADS users

I am trying to display WRF output on GrADS and I get an Error - Entire Grid Undefined for all variables
WRF was run successfull, with no errors.

Attached is my ctl file.?

I have tried doing the trouble shooting provided in the WRF manual (removing the second line option byteswapped ) but with no success.

Is there anyone who could know what is the problem?

Thank in advance
