Dear Soma,<br>
I think the matter is in the line:<br>
<br>
filedimdef(ncdf,"time",-1,True)<br>
<br>
You should change to<br>
<br>
filedimdef(fout,"time",-1,True)<br>
<br>
I hope I could help you!<br>

'latitude', 'longitude', 'level' and 'time' are named as variable's dimensions in input file which is very clear from printVarSummary of the data. I modified the code as per your hints. Modified code is attached below. Kindly inform me where I am doing wrong again.<br>

Hi Soma,<br>
<br>
please, reply always to ncl-talk that everybody is able to follow.<br>
<br>
The problem is, that you changed the name of the level dimension to lev. ZMT has the dimension name level. Change lev to level and it should work or<br>
<br>
ZMT!1 = "lev"<br>
ZMT&lev = lev<br>

Hi all,<br>
<br>
I wanted to calculate mean vertical wind shear for each pressure level<br>
(950-100mb). I used u and v wind component from the NCEP Climate Forecast<br>
System Reanalysis (CFSR) 6-hourly Products.<br>
<br>
I am getting the following errors:<br>
fatal:Number of subscripts do not match number of dimensions of<br>
variable,(2) Subscripts used, (3) Subscripts expected<br>
fatal:["Execute.c":8575]:Execute: Error occurred at or near line 41 in file<br>
test_vws_eachlevel.ncl<br>
<br>
Number of subscripts do not match number of dimensions of variable,(2)<br>
Subscripts used, (3) Subscripts expected<br>
fatal:["Execute.c":8575]:Execute: Error occurred at or near line 47 in file<br>
test_vws_eachlevel.ncl<br>
<br>
Please help.<br>
<br>
Cheers,<br>

Hi,<br>
<br>
Unfortunately, the script you sent does not align with the line numbers of<br>
the error messages -- line 47 is a blank line. In any case, the error<br>
message is pretty self-explanatory -- you are making reference to a 3D<br>
variable as though it were a 2D variable. You might place a few strategic<br>
"printVarSummary()" statements for the variables involved to make sure your<br>
variables are what you think they are.<br>
<br>
Hope that helps...<br>
Rick<br>

Hello,<br>
<br>
Is there any function/script available to calculate LCL height and draw the<br>
region of LCL, CAPE ,CINE and LFC on skew-T diagram along with wind speed<br>
and direction.<br>
<br>
Kindly inform me.<br>
<br>
Thanks,<br>
