[gradsusr] STREAM FUNCTION

[kalyan chakravarthy]

Dear All,


I have global wind data at 2.5 degrees resolution and need to calculate

and display a mean meridional wind stream function (rising and sinking

motions of three cells) in GrADS. I have choose domain -90S/90N and 40/110E.

Then I want to calculate and display psi.I'm having trouble figuring
out a way to

structure this within GrADS. How to calculate psi from wind components.

Any suggestions, or a script for me to use?  Thanks.
