[gradsusr] Potential vorticity computation

[Ricardo Hallak]

Hi, 

not tested, however my guess is that you should use 
lat instead y 
when defining: 
'define coriol=2*7.29e-5*sin(y*3.1415/180)' 

Other commands in the script seem ok. 

Hope it works, 
Ricardo

| Any scripts for potential vorticity computation for the layer between
| surface to 600 hPa. I have zonal, meridional wind and air
| temperature at different levels to compute the same. I tried with
| the scripts that are already therein gradsusr archives. Not seems to
| work. One such script is attached herewith. Any help in this regard
| will be much appreciated. Thanks.
