Plotting Stream Function in GrADS?

[Thomas Spengler]

Dear GrADS User,

I would like to plot the stream function of a velocity field u and v, or
even better the perturbation stream function in GrADS.

I know when setting 'gxout stream' one can plot stream lines by 'd u;v'.
I would now like to plot the corresponding streamfunction. Is there any
tool available for GrADS to easily plot that function?

Thanks so much for your help!

Best,
Thomas
